- CVE-2026-18943, 12 Aug 2026
- The WPC Admin Columns WordPress plugin before 2.3.4 does not have authorisation checks in one of its AJAX actions, allowing users with a role as low as subscriber to read arbitrary user, post and term metadata, including data belonging to administrators. CVE record
- CVE-2025-3418, 12 Apr 2025
- The WPC Admin Columns plugin for WordPress is vulnerable to privilege escalation in versions 2.0.6 to 2.1.0. This is due to the plugin not properly restricting user meta values that can be updated through the ajax_edit_save() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update their role to that of an administrator. CVE record
What to do if you run WPC Admin Columns
If you run WPC Admin Columns, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
