Credential compromise via missing endpoint authentication
Published Oct 13, 2026 · Updated Oct 13, 2026
Missing authentication in Rapid7 Metasploit Framework before 6.5.5 allows remote attackers to alter credentials via its REST API. CredentialServlet's update_credential and delete_credentials handlers process untrusted requests without calling warden.authenticate! and return credential data. Exploitation requires a reachable, database-backed web service and no authentication, exposing stored secrets to disclosure, modification, and permanent deletion.
