CVE-2026-44237

CVSS v4.0

FreePBX is an open source IP PBX. Prior to 17.0.8, the FreePBX api module's OAuth2 implementation does not sufficiently validate client credentials during token issuance. Knowledge of a valid client id is required. The validateClient() method in ClientRepository.php unconditionally returns true, allowing any party with knowledge of a valid client id to obtain OAuth2 access tokens without providing the correct client secret. This vulnerability is fixed in 17.0.8.
