Unit 42 researchers identified critical security risks in the implementation of OpenID Connect (OIDC) within CI/CD environments, revealing vulnerabilities that threat actors could exploit to access restricted resources. Key issues include misconfigured identity federation policies, reliance on user-controllable claim values, and the potential for poisoned pipeline execution. Organizations are urged to strengthen their OIDC configurations and security practices to mitigate these risks.
