What is CVE-2025-55210?

FreePBX, an open-source GUI for managing Asterisk, is susceptible to a privilege escalation vulnerability in its API modules prior to versions 17.0.5 and 16.0.17. The flaw allows authenticated users with access to the REST and GraphQL APIs to create forged JSON Web Tokens (JWTs) using the api-oauth.key private key. This can enable attackers, even those with lower privileges, to bypass standard authorization controls by requesting any scope they desire, as long as they know a valid JWT ID (jti) that corresponds to an existing entry in the database. This capability poses a significant risk for unauthorized access to sensitive functionalities within FreePBX.
