CVE-2026-17121IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to uncontrolled recursion.Ibm Vios Élevée CVSS 7.5 CVE-2026-40345deepmerge-ts is a typescript library providing functionality to deep merging of javascript objects. Prior to 8.0.0, the deepmerge, deepmergeCustom, deepmergeInto, and deepmergeIntoCustom APIs do not track visited objects or object pairs when recursively merging records. When two input values contain self-references at the same property path, the merge logic repeatedly revisits the same pair until Node.js raises RangeError: Maximum call stack size exceeded. Applications that merge attacker-controlled recursive object graphs can synchronously crash the affected process or cause repeated worker restarts. Plain JSON input alone cannot create the recursive graph required to trigger the issue. This issue is fixed in version 8.0.0.Analyse NVD en cours Élevée CVSS 8.2 CVE-2026-54623django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.8, the move_plugin endpoint in cms/admin/placeholderadmin.py accepts an attacker-controlled plugin_parent value without rejecting a plugin’s own identifier or a descendant identifier. A staff user with plugin-change permission under CMS_PERMISSION can create a parent_id cycle in the plugin tree. The _get_descendants_cte and _get_ancestors_cte queries in cms/models/pluginmodel.py have no cycle guard, so get_descendants() and later rendering, copy, or delete operations can recurse indefinitely or reach a database recursion limit, corrupting the tree and consuming request workers. This issue is fixed in versions 5.0.8.Analyse NVD en cours Élevée CVSS 7.1 CVE-2026-69220The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java permits ValueReader.readTable and ValueReader.readArray to call ValueReader.readFieldValue recursively for AMQP table type F and AMQP array type A values without a nesting-depth limit. A malicious AMQP server or network intermediary can send approximately 580 nested table levels in the pre-authentication connection.start frame, fitting within the default 131072-byte frame maximum, to trigger StackOverflowError. The error terminates the client input processing thread and causes denial of service. This issue is fixed in version 5.33.1.Analyse NVD en cours Élevée CVSS 8.7 CVE-2026-74783Scriban versions 6.6.0 through 7.2.0 contain a non-enforcing ExpressionDepthLimit guard that fails to stop recursive descent parsing of deeply nested expressions. Attackers can supply templates with deeply nested parentheses, array initializers, object initializers, or unary operators to trigger an uncatchable StackOverflowException that immediately terminates the host process.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-74787Scriban before 7.0.0 contains an uncontrolled recursion vulnerability in the object.to_json builtin function that lacks depth limits and circular reference detection. Attackers can craft templates with self-referencing objects to trigger unbounded recursion, causing a StackOverflowException that fatally terminates the hosting .NET process.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-74792Scriban before 7.0.0 (affected versions <= 6.6.0) contains a stack overflow vulnerability in nested array initializer parsing. Deeply nested array initializers recurse through a path (ParseArrayInitializer → ParseExpression → ParseArrayInitializer) that is not covered by the ExpressionDepthLimit counter added in the fix for GHSA-wgh7-7m3c-fx25. An attacker who can supply untrusted input to Template.Parse can trigger an uncatchable StackOverflowException that immediately terminates the process, even with the default ExpressionDepthLimit enabled.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-74794Scriban before 6.6.0 contains an infinite recursion vulnerability in object rendering when the ObjectRecursionLimit property defaults to unlimited. Attackers can supply circular reference objects to the template context, exhausting stack space and triggering an uncatchable StackOverflowException that terminates the hosting process.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-74795Scriban before 6.6.0 contains an uncontrolled recursion vulnerability in its recursive-descent parser. The parser does not enforce a default expression depth limit (the ExpressionDepthLimit property in ParserOptions defaults to null/disabled), so an attacker who controls template input can supply a deeply nested template (e.g., thousands of nested parentheses or blocks) that exhausts thread stack space and raises a StackOverflowException. Because a StackOverflowException cannot be caught in .NET, this causes immediate, unrecoverable termination of the hosting process, resulting in a denial of service. Applications that process untrusted or user-supplied templates can be exploited remotely without authentication.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-17177IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote attacker to cause a denial of service due to uncontrolled recursion.Ibm Db2 Mirror For I Élevée CVSS 7.5 CVE-2026-73566node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and no segment cap when tar.t(...) or tar.x(...) receives a non-empty member-selection list. A crafted GNU L or PAX x long-path header with thousands of slash-separated segments reaches this.filter(entry.path, entry) in Parser[CONSUMEHEADER] in src/parse.ts before Unpack[CHECKPATH] applies maxDepth, causing an uncatchable RangeError stack overflow that terminates asynchronous and streaming Node.js consumers. This issue is fixed in version 7.5.21.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-62295HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the JSON utility parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth for arrays or objects. As a result, a small but deeply nested, syntactically valid FHIR JSON document can trigger unbounded readArray() or readObject() recursion, raising a StackOverflowError before structural validation runs. An attacker who can submit JSON resources for validation can thus crash the request thread, and services that do not isolate StackOverflowError safely may experience worker loss or process instability — a denial-of-service condition. This issue is fixed in version 6.9.11.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-62296HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, XhtmlParser.java imposes no maximum element nesting depth, so a deeply nested text.div narrative triggers unbounded recursion between parseElementInner() and parseElement(), raising a StackOverflowError. An attacker who can submit FHIR resources containing such narratives can thus crash a parsing or validation worker thread, affecting validator services and any application that parses attacker-supplied FHIR JSON or XML. This issue is fixed in version 6.9.11.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-32327A bug in APR-util version 1.6.3 (and earlier) allows a stack recursion attack against any library consumer which parses XML from untrusted sources and uses the apr_xml_quote_elem() function.
Users are recommended to upgrade to version 1.6.4, which fixes this issue.Apache Apr-util Critique CVSS 9.1 CVE-2026-15996A denial of service vulnerability was identified in GitHub Enterprise Server that allowed an unauthenticated attacker to cause excessive CPU consumption and exhaust the pool of request-handling worker processes by sending a crafted form-encoded HTTP POST request containing deeply nested parameters. Because request parameters were parsed before routing and authentication, any POST endpoint could be used to trigger the condition, which could render the instance unresponsive. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.21 and was fixed in versions 3.20.3, 3.19.7, 3.18.10, and 3.17.16.Github Enterprise Server Élevée CVSS 7.5 CVE-2026-61483** UNSUPPORTED WHEN ASSIGNED ** Uncontrolled Recursion vulnerability in Apache Lucy.

This issue affects Apache Qpid Broker-J: through 10.0.1.
Users are recommended to upgrade to version 10.1.0, which fixes the issue.Apache Qpid Broker-j Élevée CVSS 7.5 CVE-2026-13506In Bouncy Castle for Java before 1.85, Lazy ASN.1 sequence forcing resets nesting-depth guard. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bc-fips 1.0.2.7 (1.0.X series), 2.0.2 (2.0.X series) and 2.1.3 (2.1.X series).Bouncycastle Bc-java Élevée CVSS 8.7 CVE-2026-59645In Bouncy Castle for Java before 1.85, OER parser recurses without depth limit on self-referential IEEE 1609.2 schema. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bcutil-fips 2.0.7 (2.0.X series) and 2.1.7 (2.1.X series).Bouncycastle Bc-java Élevée CVSS 8.7 CVE-2026-18140Uncontrolled recursion in the unknown-key skip path of the aws-smithy-json runtime crate before 0.62.7, which the smithy-rs code generator invokes from every generated struct deserializer, might allow remote unauthenticated users to cause a denial of service (process abort via stack exhaustion) via a single small HTTP request containing deeply nested JSON to a smithy-rs generated server.
To remediate this issue, users should upgrade to aws-smithy-json 0.62.7 or later and rebuild.Amazon Aws-smithy-json Élevée CVSS 7.5 CVE-2026-58178The Apache Traffic Server ESI plugin can recurse without bound and fetch attacker-controlled URLs.
This issue affects Apache Traffic Server: from 8.0.0 through 8.1.9, from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3.
Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue.Apache Traffic Server Élevée CVSS 7.5 CVE-2026-67215cJSON through 1.7.19 is vulnerable to uncontrolled recursion leading to stack exhaustion when an untrusted RFC 6902 JSON Patch is applied via cJSONUtils_ApplyPatches() or cJSONUtils_ApplyPatchesCaseSensitive(). A patch containing add and copy operations grafts duplicated subtrees to amplify document depth beyond the parser's nesting limit: cJSON_Delete() recurses with no depth bound, and the cJSON_Duplicate() guard CJSON_CIRCULAR_LIMIT is set to 10000, ten times the parser's 1000-level nesting limit and high enough to overflow a default thread stack. An attacker who can supply the patch document can crash the process, resulting in denial of service.Davegamble Cjson Élevée CVSS 7.5 CVE-2026-66920Pivotick contains an uncontrolled-recursion vulnerability when processing caller-supplied graph and node data. The affected graph algorithms recursively traversed graph edges, while the JSON viewer recursively processed each level of a node’s data structure. A specially crafted graph containing an excessively long path, deeply nested properties, or circular object references could therefore exhaust the JavaScript call stack when Pivotick calculates a layout or displays a node in the inspection modal.
Successful exploitation may cause an uncaught exception, freeze the affected page, or crash the browser tab, resulting in a client-side denial of service. No confidentiality or integrity impact has been identified.
The patch replaces the recursive graph traversals with iterative stack-based implementations and limits the reachability calculation to 1,000,000 edge traversals. It also limits JSON rendering to 64 levels and detects circular references before descending further into an object. Élevée CVSS 8.2 CVE-2026-58227The Erlang/OTP ssl application does not detect cycles when reconstructing an incomplete peer certificate chain during a TLS or DTLS handshake. In ssl_certificate:handle_incomplete_chain/5, the received chain is passed to ssl_certificate:build_certificate_chain/5, which walks issuer relationships via ssl_certificate:do_certificate_chain/7 with no cycle detection and no depth limit. When the peer supplies two mutually cross-signed certificates in unordered form (A issues B, B issues A), the issuer lookup alternates between the two certificates and the pair of functions recurses indefinitely, growing the call stack and chain accumulator without bound.
An unauthenticated remote attacker can send a crafted certificate chain in a TLS or DTLS Certificate handshake message to exhaust available memory and crash the BEAM node. Only a TCP connection and a partial handshake are required; no authentication or completed handshake is needed, and both TLS/DTLS servers and clients are affected when processing peer certificate messages.
This issue affects OTP from OTP 23.2 before OTP 29.0.4, OTP 28.5.0.4 and OTP 27.3.4.15, corresponding to ssl from 10.2 before 11.7.4, 11.6.0.4 and 11.2.12.11.Erlang Erlang\/otp Élevée CVSS 8.7 CVE-2026-64219In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Validate payload length and link_index in dc_process_dmub_aux_transfer_async
[Why&How]
dc_process_dmub_aux_transfer_async() copies payload->length bytes into a
16-byte stack buffer (dpaux.data[16]) guarded only by an ASSERT(), which
is a no-op in release builds. If a caller ever passes length > 16 this
results in a stack buffer overflow via memcpy.
Additionally, link_index is used to dereference dc->links[] without
bounds checking against dc->link_count, risking an out-of-bounds access.
Replace the ASSERT with a hard runtime check that returns false when
payload->length exceeds the destination buffer size, and add a bounds
check for link_index before it is used.
(cherry picked from commit ba4caa9fecdf7a38f98c878ad05a8a64148b6881)Linux Linux Kernel Élevée CVSS 7 CVE-2026-63760SurrealDB before 3.1.0 fails to enforce the configured recursion depth limit in the value and JSON parser when processing nested braces, brackets, or parentheses. Unauthenticated attackers can send deeply nested JSON payloads to the WebSocket /rpc endpoint to exhaust server memory and crash the process.Surrealdb Élevée CVSS 7.5 CVE-2026-64194Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains.
Net::DNS::DomainName::decode follows RFC 1035 compression pointers by recursing into itself with no depth limit. It is possible to construct a name which saturates the call stack (at least with larger TCP responses), leading to a potential Denial of Service.
The guard `$link < $offset` prevents forward and circular chains, but still allows arbitrarily long backward chains. The per-offset cache (`$cache`) is populated at the start of each call and short-circuits only re-traverses of the same offset - the initial descent through a fresh chain still recurses at full depth.
A crafted packet can chain two-byte compression pointers so that each one points two bytes earlier than the previous, producing a chain length of `offset / 2`. For the 14-bit pointer field (max offset 16383) this gives up to ~8191 recursive frames. For a TCP DNS message the limit is the 16-bit length field (~32767 frames). Perl's default C stack handles only a few thousand frames; beyond that the process receives SIGSEGV or similar, which is a denial-of-service for any application parsing untrusted DNS data.
The vulnerability is triggered by `Net::DNS::Packet->new(\$wire)` i.e. any point where the library decodes a DNS message from the network. Élevée CVSS 7.5 CVE-2026-53395In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix dead ACL conflict guard in nfsd4_create
nfsd4_create() steals create->cr_dpacl/cr_pacl into the local
nfsd_attrs via the designated initializer, then immediately sets the
source pointers to NULL. The subsequent conflict guard tests the
already-nilled source fields, making it permanently dead code:
if (create->cr_acl) {
if (create->cr_dpacl || create->cr_pacl) /* always false */
When a client encodes both FATTR4_WORD0_ACL and
FATTR4_WORD2_POSIX_{DEFAULT,ACCESS}_ACL in the same CREATE fattr
bitmap, nfsd4_acl_to_attr() overwrites attrs.na_pacl/na_dpacl without
releasing the originals, leaking two posix_acl slab objects per
request. Repeated requests cause unbounded slab exhaustion.
Fix by checking attrs.na_dpacl/na_pacl (the stolen values) instead of
the nilled create->cr_dpacl/cr_pacl, matching the correct pattern
already used in nfsd4_setattr().Linux Linux Kernel Élevée CVSS 7.5 CVE-2026-45133Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, when the parser is exposed to attacker-controlled input, deeply nested mappings or sequences cause both the block-level (Parser::parseBlock()) and inline (Inline::parseSequence() / Inline::parseMapping()) parsers to recurse without a depth limit. A crafted document exhausts the PHP stack and crashes the worker. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.Sensiolabs Symfony Élevée CVSS 7.5 CVE-2026-40007Uncontrolled Recursion, Uncontrolled Resource Consumption vulnerability in Apache IoTDB.
When pipe_air_gap_receiver_enabled=true, the IoTDB AirGap receiver's
readLength method calls itself recursively each time it recognises the
E-language prefix in socket data, with no depth limit. An unauthenticated
attacker can send a stream of repeated E-language prefixes that drives the
recursion arbitrarily deep, exhausting the receiver thread's JVM stack and
raising StackOverflowError.
This issue affects Apache IoTDB: from 1.0.0 before 2.0.10.
Users are recommended to upgrade to version 2.0.10, which fixes the issue. Élevée CVSS 7.5 CVE-2026-38970pdfcpu through v0.11.1 contains an uncontrolled-recursion denial-of-service issue in pkg/pdfcpu/model/parse.go. The parser descends recursively through nested PDF objects, including arrays, via ParseObjectContext() and parseArray() without enforcing a maximum nesting depth. Élevée CVSS 7.5 CVE-2026-53329In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Use krealloc_array() in dal_vector_reserve()
[Why & How]
dal_vector_reserve() computes the allocation size as
"capacity * vector->struct_size" using uint32_t arithmetic, which can
silently wrap to a small value on overflow. This would cause krealloc to
return a smaller buffer than expected, leading to heap overflows on
subsequent vector appends.
Replace krealloc() with krealloc_array() which performs an internal
overflow check and returns NULL on wrap, preventing the issue.
(cherry picked from commit 37668568641ccc4cc1dbca4923d0a16609dd5707)Linux Linux Kernel Élevée CVSS 7 CVE-2026-49451The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. From 2.0.0-preview11 until 2.7.5 and 3.5.4, a small OpenAPI document containing a circular schema reference can cause process termination through stack overflow in Microsoft.OpenApi. The issue affects OpenAPI document parsing through public OpenAPI.NET reader APIs and has been confirmed across both JSON and YAML reader paths. This vulnerability is fixed in 2.7.5 and 3.5.4.Analyse NVD en cours Élevée CVSS 7.5 CVE-2026-57081Net::BitTorrent versions through 2.1.0 for Perl allow remote memory exhaustion via deeply nested bencoded input.
bdecode recurses once per nested list or dictionary level with no depth cap, and each recursive call receives the remaining buffer by value while the list and dictionary branches capture the whole remainder, so every live recursion frame keeps its own copy of the shrinking buffer (O(N^2) bytes for an N-deep input). The decoder runs on every untrusted bencode source: .torrent files, BEP09 metadata fetched from peers, DHT messages, and tracker responses.
A bencoded input of roughly 150,000 nested lists (about 150 KB on the wire) drives multi-gigabyte peak memory, so one short message from any peer, or one crafted .torrent file or magnet link, terminates the client. Élevée CVSS 7.5
