Where this data comes from
- 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.
- Plugin versions, update dates and install counts: the wordpress.org Plugins API.
- These lists cover the 3,948 plugins in our catalogue, not every plugin on wordpress.org. We only list a CVE for a plugin when its references or its advisory name that exact plugin, so a few real issues may be missing. Spot an error? Email Daniel.
