CVE-2026-94212: Apache APISIX cryptographic signature verification bypass in saml-auth

CVE-2026-94212 · Severity: info · Published 2026-10-01

Apache APISIX is an API gateway that routes and protects HTTP traffic. The saml-auth plugin secures routes by validating user identity through SAML authentication tokens. A flaw in cryptographic signature verification allows any attacker to forge SAML tokens and impersonate legitimate users, gaining unauthorized access to protected routes and potentially exposing sensitive data or performing unauthorized actions.

How to fix

Fixed in: Apache APISIX 3.19.0

Technical details

The saml-auth plugin in Apache APISIX fails to properly verify cryptographic signatures on SAML assertions under default configuration. An unauthenticated network attacker can craft malicious SAML tokens that bypass signature validation, allowing impersonation of any user. This affects versions 3.17.0 through 3.18.0, and is fixed in version 3.19.0.

Affected products

Apache APISIX 3.17.0 through 3.18.0
