OpenID Connect

Release date 2025/07/03

Bugfix

• Fixed an issue where caused IdP to report invalid redirect_uri errors when config.redirect_uri was not configured and the uri path contained spaces.

• Fixed an issue where the OIDC plugin caused the third-party IDP to throw an error during logout attempts if the session had already been invalidated. Added the client_id to the logout URL to ensure the logout request is sent to the correct client, preventing such errors.

Performance

• improved the performance of signature verification.
