- CVE-2026-7654, 5 Jun 2026
- The Admin Columns plugin for WordPress is vulnerable to PHP Object Injection leading to Remote Code Execution in versions up to and including 7.0.18. This is due to the use of `unserialize()` without an `allowed_classes` restriction in the `IdsToCollection::get_ids_from_string()` function, which processes attacker-controlled post meta values without proper validation. This makes it possible for authenticated attackers with Contributor-level access and above to inject a serialized PHP object into a post's custom meta field and trigger arbitrary code execution by exploiting a bundled POP gadget chain, resulting in remote code execution as the web server user. CVE record
- CVE-2021-24365, 12 Jul 2021
- The Admin Columns WordPress plugin Free before 4.3.2 and Pro before 5.5.2 allowed to configure individual columns for tables. Each column had a type. The type "Custom Field" allowed to choose an arbitrary database column to display in the table. There was no escaping applied to the contents of "Custom Field" columns. CVE record
- CVE-2021-24366, 21 Jun 2021
- The Admin Columns WordPress plugin before 4.3 and Admin Columns Pro WordPress plugin before 5.5.1 do not sanitise and escape its Label settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup) CVE record
What to do if you run Admin Columns
If you run 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.
