Where this data comes from

Version, last update, installs: wordpress.org/plugins/gutenberg (Plugins API), fetched 2026-11-01.
Vulnerabilities: NIST National Vulnerability Database (NVD), checked 2026-11-01. 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.
