CVE-2026-57817
A flaw in Apache CXF allows for Authorization Code Substitution/Injection attacks during the OpenID Connect Hybrid Flow. The vulnerability occurs because the cxf-rt-rs-security-sso-oidc library (and the broader cxf component) fails to enforce the validation of the c_hash parameter, as required by...
CVE-2026-63687: Insufficient Verification of Data Authenticity
Apache CXF's JwtRequestCodeFilter copies all claims from a signed request JWT into the authorization parameter map without excluding security-sensitive parameters. A client that can produce a validly-signed request JWT e.g., one whose clientsecret is known or compromised can thereby substitute th...
keycloak: org.keycloak.protocol.oidc: HTTP Parameter Pollution in OIDC redirect URI allows response parameter duplication - #GHI-604
A flaw was found in Keycloak, an open-source identity and access management solution. When a client application is configured to accept broad redirect Uniform Resource Identifiers URIs, a remote attacker can manipulate the authentication process by crafting a special web address. If a user clicks...
keycloak: Keycloak: Security policy bypass in JWE-encrypted request object processing
A flaw was found in Keycloak. When a JSON Web Encryption JWE encrypted request object is submitted, Keycloak may incorrectly process unsigned claims if the decrypted content is raw JSON, bypassing the configured signature policy. This allows a remote attacker to submit unauthorized claims, leadin...
