The self-hosted forge Forgejo shipped versions 16.0.4 and 15.0.8 on September 10 to fix a critical RCE born of template expansion, alongside three authorization flaws that share the same root cause. Everything on 16.0.3 or earlier must be patched, and fine-grained token inventories need a review.
On September 9, 2026, SAP shipped fixes for four critical flaws, including CVE-2026-44756 (CVSS 10.0), a memory-corruption bug in Extended Passport processing that yields unauthenticated remote code execution across three protocols at once. Basis teams should patch the SAP kernel first, ahead of any network segmentation effort.
The September 8, 2026 Patch Tuesday fixes nine remote code execution flaws in Windows DNS Server, including CVE-2026-69730, a CVSS 9.8 use-after-free triggerable with a single forged packet. Patch the servers running the DNS role first and segment port 53 before a public exploit appears.
Sansec documents StyleSmuggler, a Magento and Adobe Commerce zero-day exploited since September 4, 2026 that runs code without authentication through the template engine and installs a persistent backdoor. Adobe has published no CVE and no patch yet: disable GraphQL on your stores while waiting for the September 8 bulletin.
On 2 September 2026 Cisco disclosed CVE-2026-20212, a CVSS 9.8 flaw that leaves TCP ports 43210 and 43211 on ten Nexus 9000 switches reachable for unauthenticated remote code execution as root. Apply an iACL on both ports and the Live Protect lp00031 shield now, then check your release in the Software Checker.
On September 1, 2026, VulnCheck observed mass exploitation of CVE-2026-0768, an unauthenticated remote code execution flaw in Langflow, used to harvest OpenAI and AWS keys from exposed instances. It is the sixth Langflow flaw exploited since January: any instance patched below 1.11.6 must be treated as compromised.
On 27 August 2026, GiveWP fixed CVE-2026-82222, a three-bug chain that turns a WordPress donation form into remote command execution with no real authentication. Administrators must upgrade to 4.16.7.2 and check for rogue accounts, even on sites where registration was disabled.
On 30 June 2026, Citrix rated CVE-2026-8452 as a memory overflow. On 14 August, WatchTowr showed it leads to pre-authentication code execution, and on 26 August CISA added it to the KEV catalog with a 29 August deadline. Appliances configured as VPN or AAA servers must be patched today, without waiting for official confirmation of exploitation.
CVE-2026-60004, a critical code-injection flaw in Gitea, has been exploited in the wild since August 25, 2026: an attacker can run shell commands as the forge’s system user. Self-hosted instances with open registration are hit first; the fix comes down to an upgrade and a disable switch.
A deserialization flaw in Entra ID, Microsoft’s cloud identity service, allowed unauthenticated remote code execution — rated CVSS 10.0 and fixed server-side with no customer action. CISOs need to understand what "no action required" actually demands of them.
Ray’s anti-browser defense was a User-Agent header check that Firefox and Safari let you forge through the fetch API. Combined with DNS rebinding, it becomes a remote code execution triggered by a single page visit — added to CISA’s KEV catalog on August 17, 2026 with a fix deadline of August 20.
CVE-2026-73678, scored CVSS 10, lets an attacker with no account run system commands on the MindsDB platform through the Anton agent’s scratchpad tool. If you expose a MindsDB instance, cut public access before even waiting for a patch.
Disclosed on August 12, 2026, an unauthenticated SQL injection in GeoServer’s jsonArrayContains function can lead to remote code execution, and no patch is available yet. Attackers are already probing exposed instances: isolate yours before the fix lands.
On August 2, 2026, Gitea shipped a critical fix for CVE-2026-59774, a path traversal that lets an unauthenticated attacker read any server file via Org-mode markup rendering on a public repository. Worse: by reading the INTERNAL_TOKEN from app.ini, the attacker can escalate to remote code execution. Every self-hosted Gitea administrator must patch and rotate secrets immediately.
A vulnerability chain in WordPress Core, dubbed XSS2Shell, lets an unauthenticated attacker turn a single failed login attempt into full PHP remote code execution. The 7.0.3 patch landed August 6, 2026 — 43% of the web needs to apply it now.
On August 1, 2026, the Rails team patched CVE-2026-66066, a critical Active Storage vulnerability that allows unauthenticated arbitrary file read and RCE escalation via libvips. Akamai named the chain 'KindaRails2Shell' and confirmed full remote-code-execution potential.
CVE-2026-16723 (CVSS 9.0) enables unauthenticated RCE on Fastjson 1.x with no patch forthcoming — ever. Enable SafeMode immediately and plan your Fastjson 2.x migration. Here is the three-step response plan.
CVE-2026-61511 enables unauthenticated PHP code execution through template rendering in vBulletin 5.x and 6.x. A public exploit exists, and the 5.x branch will receive no fix whatsoever.
Broadcom disclosed three critical VMware vulnerabilities on July 29, 2026 — a VMXNET3 VM escape and two unauthenticated RCE flaws targeting vCenter. Patch immediately: compromising vCenter gives an attacker total control over your entire virtualized infrastructure.
JetBrains disclosed CVE-2026-63077 on July 27, 2026 — a CVSS 9.8 unauthenticated remote code execution flaw affecting every on-premises TeamCity instance. No active exploitation has been detected yet, but the clock is ticking: TeamCity's history with state-sponsored attackers makes this a drop-everything patch scenario.
