SCA: security update for admidio/admidio (GHSA-25cw-98hg-g3cg)

high Tenable Self-Hosted Container Security Plugin ID 440976

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Admidio is an open-source user management solution. Prior to version 5.0.9, the Admidio SAML Identity
 Provider implementation discards the return value of its validateSignature() method at both call sites
 (handleSSORequest() line 418 and handleSLORequest() line 613). The method returns error strings on failure
 rather than throwing exceptions, but the developer believed it would throw (per comments on lines 416 and
 611). This means the smc_require_auth_signed configuration option is completely ineffective — unsigned or
 invalidly-signed SAML AuthnRequests and LogoutRequests are processed identically to properly signed ones.
 This issue has been patched in version 5.0.9. (CVE-2026-41669)

Solution

Update the admidio/admidio library and its related packages to version 5.0.9 or later.
