About this data

Where it comes from
Each row is a record from the CVE List, published by the organization that handled the report: most often Wordfence, Patchstack or WPScan. The CVE ID links to that publisher's advisory.
What is included
CVEs published since January 1, 2024 for WordPress core, plugins and themes, premium ones included. Vulnerabilities that never received a CVE ID are not listed, and rejected CVEs are removed.
Severity
The CVSS 3.1 base score set by the publisher, or by CISA when the publisher gave none. "No login needed" means the score assumes an attacker without an account.
Affected versions
The range the publisher marked as vulnerable. When the record also names the first fixed release, it is shown under the range. If your version is newer than every affected one, that CVE does not apply to you.
Updates
Every day, after the CVE List publishes its end-of-day changes.
