High CVSS 7.1

CVE-2026-9081

Langflow

IBM Langflow OSS 1.0.0 through 1.10.3, and 1.0.0 through 1.10.3 contains a Server-Side Request Forgery (SSRF) vulnerability in the validate_model_provider_key() function for the Ollama provider. The function accepts a user-supplied OLLAMA_BASE_URL parameter and passes it directly to requests.get() without validation, scheme/host allowlisting, or filtering of private IP ranges (loopback, RFC1918, link-local addresses).

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact
An attacker can read sensitive data and alter some data.
Weakness
The server issues a request to an attacker-chosen address, reaching into the internal network (SSRF).
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.
