Openid

OpenID authentication frameworks and libraries span multiple language implementations and deployment contexts, from OpenID Connect standards to Ruby and Java bindings, where their role in federated identity makes vulnerabilities in the protocol or parser a broad-impact concern. Vulnerabilities affecting this vendor skew toward serious outcomes and frequently acquire public exploit code, reflecting both the authentication-critical nature of the code and the attack surface presented by protocol parsing and redirect handling. The recurring weaknesses cluster around code injection, improper input validation, and open-redirect conditions that are characteristic of identity-federation implementations. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
