CVE-2026-25554
OpenSIPS 3.1 <= 3.6.4 auth_jwt SQL Injection Enables JWT Authentication Bypass
Description

OpenSIPS versions 3.1 before 3.6.4 containing the auth_jwt module (prior to commit 3822d33) contain a SQL injection vulnerability in the jwt_db_authorize() function in modules/auth_jwt/authorize.c when db_mode is enabled and a SQL database backend is used. The function extracts the tag claim from a JWT without prior signature verification and incorporates the unescaped value directly into a SQL query. An attacker can supply a crafted JWT with a malicious tag claim to manipulate the query result and bypass JWT authentication, allowing impersonation of arbitrary identities.

Solution
Update OpenSIPS to a version with the auth_jwt module patched to properly handle JWT claims before SQL queries.
  • Update OpenSIPS to version 3.6.4 or later.
  • Ensure the auth_jwt module is updated via commit 3822d33.
  • Verify SQL database backend configuration for security.
