Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Admidio before 5.0.11 contains an authentication bypass vulnerability in the forum module when configured in login-only mode. The access control logic in modules/forum.php fails to validate the login-only configuration state, allowing unauthenticated attackers to read forum topics and posts by directly accessing the module with read-only parameters.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-306

A sensitive function is reachable with no authentication at all, so anyone who finds the endpoint can use it. These are routinely discovered by automated scanning. The fix is to require and enforce authentication on every privileged path, with no exceptions left open.

Recommended fix High confidence

Admidio 5.0.11 or later

  1. 1. Back up your Admidio database and all web files before proceeding.
  2. 2. Download Admidio version 5.0.11 or later from the official source (admidio.org).
  3. 3. Extract the downloaded package.
  4. 4. Replace the existing Admidio installation files with the new version, preserving your configuration files and any customizations.
  5. 5. Run any available database migration scripts included in the upgrade.
  6. 6. Verify the forum module is functioning correctly with login-only mode enabled.
  7. 7. Test that unauthenticated access to the forum module is now properly blocked.
