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
Bludit is a content management system. Versions prior to 3.22.0 have a Broken Access Control flaw where active sessions remain valid even after the corresponding user account has been physically deleted from the database. This "Ghost Session" allows revoked users to maintain full unauthorized access to the system. Version 3.22.0 fixes the issue.

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.

dbcve analysis
How this class of weakness works · CWE-285

The application confirms who you are but does not properly check whether you are permitted to perform a given action, so authenticated users reach functions or data meant for others. Attackers test roles and object references to find the gap. Remediation is an authorization check on every request, evaluated against the acting user's actual permissions.

Recommended fix Moderate confidence

Bludit 3.22.0

  1. 1. Identify the current Bludit version by checking the version file or admin dashboard
  2. 2. Create a complete backup of the Bludit installation directory and database
  3. 3. Download Bludit version 3.22.0 or later from the official repository at https://github.com/bludit/bludit/releases
  4. 4. Extract the new version files and replace the existing installation files
  5. 5. Verify the version has been updated after the upgrade
  6. 6. Test that previously deleted user accounts can no longer access the system (the ghost session vulnerability should be fixed)
Caveat Standard CMS upgrade - test in staging environment first
