The Doorkeeper gem before 4.2.0 for Ruby might allow remote attackers to conduct replay attacks or revoke arbitrary tokens by leveraging failure to implement the OAuth 2.0 Token Revocation specification.

Security readout for executives and security teams

Ruby applications using the Doorkeeper gem before 4.2.0 may mishandle OAuth token revocation. An attacker could potentially replay requests or revoke tokens they should not control. Business impact depends on whether the application uses Doorkeeper as an OAuth provider and exposes token revocation workflows. Exposure is most likely in Ruby/Rails services using Doorkeeper versions earlier than 4.2.0 for OAuth authorization and token revocation. Prioritize remediation for internet-facing OAuth providers or applications handling sensitive user sessions. Lower urgency if Doorkeeper is absent or unused. Mitigation focus: Upgrade Doorkeeper to version 4.2.0 or later.; Check vendor release notes and issue history for configuration-specific guidance.; Review OAuth clients and revocation endpoint exposure..
