Prior to version 5.0.8, the create_user, assign_member, and assign_user action modes in modules/registration.php approve pending user registrations via GET request without validating a CSRF token. Unlike the delete_user mode in the same file (which correctly validates the token), these three approval actions read their parameters from $_GET and perform irreversible state changes without any protection. An attacker who has submitted a pending registration can extract their own user UUID from the registration confirmation email URL, then trick any user with the rol_approve_users right into visiting a crafted URL that automatically approves the registration. This bypasses the manual registration approval workflow entirely. This issue has been patched in version 5.0.8."}], "lastModified": "2026-04-01T18:31:30.673", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:admidio:admidio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "943C8893-5336-477E-9026-C55A9659B1EA", "versionEndExcluding": "5.0.8"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
