Jun 1, 20262026-06 Monthly Summary: Key security hardening patch for SAML ECP error handling in keycloak/keycloak; mitigated CVE-2026-9794 by preventing leakage of client existence and configuration state in error responses. Introduced a generic error message and centralized constants to ensure secure reporting. Delivered three commits (dba79eb03fb9d634fda5e86e1613b8747f968518, 05e98366773eec60878bb2a6d5da6bc7048ac3c8, 7750e3ff823d1da8580d42c51194feb2e933b87b) addressing CVE-2026-9794 and closes #49428, #49686. Impact: reduces exposure risk in SAML ECP flows, improves security posture, without user-visible changes; minimal performance impact.

May 1, 2026May 2026 monthly summary for keycloak/keycloak: Focused on delivering key JWT-related test suite improvements and hardening critical authentication flows. Delivered a refactor and test migrations for JWT-related tests into a cleaner package structure, with enhanced credential handling and signing error paths, and migrated related OID4VC JWT Issuer Endpoint and SD-JWT Issuing Endpoint tests. Also hardened SAML 1.1 parsing to address security concerns by correcting XML handling and adding tests to guard against malformed requests, aligned with CVE-2026-7307. These efforts reduce maintenance burden, strengthen security, and improve reliability of OIDC/SD-JWT flows and downstream credential signing processes.

Feb 1, 2026February 2026 monthly summary for keycloak/keycloak: Focused delivery of two key improvements with clear business value and documentation alignment. - Key features delivered: - Enhanced Password Update Error Logging for LDAP Policy Violations: clearer cause logging for password update failures tied to LDAP policy, enabling faster triage and auditability. Commit 4036ddc837836e27b2c58591ce99dff52e953a5c (Closes #44459). - Distribution Registry Terminology Update in Docs: rename Docker Registry to Distribution Registry across docs and clarify the authentication flow for better user guidance. Commit 248c635fda599d919e36514b1f314c3ebaa2d689 (Closes #45163). - Major bugs fixed: - LDAP password update failure visibility improved by surfacing policy-violation reasons, reducing mean time to resolution for related incidents (Closes #44459). - Overall impact and accomplishments: - Improved operational visibility and faster triage of LDAP-related issues; reduced user confusion through terminology standardization; stronger auditability of password policy violations. - Technologies/skills demonstrated: - LDAP policy integration and enhanced logging, documentation standardization across the repository, and disciplined commit hygiene with signed-off commits.
