Closed plugins get no updates through WordPress, so new security holes will not be fixed for you. Keep Internal Link Builder on the latest version and remove it if you do not use it.

Is Internal Link Builder safe? Known vulnerabilities and latest version

Status: Closed 2026-01-08
Known issues on record: 2
Unpatched in latest: 0

What to do

Replace it. A closed plugin gets no updates through WordPress, so any hole found from now on stays open.
Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deleting removes its files; deactivating alone leaves them on the server.
If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.

With WP-CLI, once you have a replacement: wp plugin deactivate internal-link-builder && wp plugin delete internal-link-builder

Details from the advisory

The Internal Link Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled.
