Build a multi-product knowledge base for WordPress. Reduce support tickets with self-service docs, FAQs, and a built-in help center. — by Ajay
What to do
- Update to the latest version (3.2.4). Anything older than 3.2.1 has at least one known issue listed below. Dashboard → Updates, or Plugins → “update now”.
- If you cannot update right away, deactivate it until you can.
- Turn on auto-updates for it: Plugins → “Enable auto-updates” on its row.
- If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan.
With WP-CLI: wp plugin get knowledgebase --field=version shows what you run; wp plugin update knowledgebase updates it.

Where this data comes from
- Version, last update, installs: wordpress.org/plugins/knowledgebase (Plugins API), fetched 2026-11-04.
- Vulnerabilities: NIST National Vulnerability Database (NVD), checked 2026-11-04. This product uses data from the NVD API but is not endorsed or certified by the NVD.
- Each record links to its CVE page and to the original advisory (Wordfence, Patchstack or WPScan) where there is one. We only list a CVE here when its references or its advisory name this exact plugin, so a few real issues may be missing; none should be about a different plugin. Spot an error? Email Daniel.
