CVE-2026-41671— Admidio 授权问题漏洞

Admidio: OIDC Token Introspection Endpoint Returns Active for All Tokens Without Validation

Admidio is an open-source user management solution. Prior to version 5.0.9, the OIDC token introspection endpoint (/modules/sso/index.php/oidc/introspect) always returns {"active": true} for every request, regardless of whether a valid token is provided, whether the token is expired, revoked, or completely fabricated. The endpoint performs no authentication of the calling resource server and no validation of the submitted token. Any resource server that relies on this introspection endpoint to validate access tokens will accept all requests as authorized, enabling complete authentication bypass. Additionally, the OIDC token revocation endpoint (/oidc/revoke) returns {"revoked": true} without actually revoking any token, preventing resource servers from invalidating compromised credentials. This issue has been patched in version 5.0.9.

认证机制不恰当

Admidio 授权问题漏洞

Admidio是Admidio团队的一套开源的成员管理系统。该系统支持成员列表、事件管理、留言簿、相册和下载等功能。 Admidio 5.0.9之前版本存在授权问题漏洞，该漏洞源于OIDC令牌内省端点始终返回active为true，不验证令牌有效性，且令牌撤销端点返回revoked为true但不实际撤销令牌，可能导致完全的身份验证绕过。
