{"cve":"CVE-2026-15350","nvd":{"published":"2026-07-16T09:16:18.047","modified":"2026-07-16T14:16:48.880","status":"Deferred","description":"The The Cache Purger plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.20. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to permanently truncate the plugin's cache-purge audit log (wp-content/purge.log), destroying the entire cache-purge audit history. The tcp_log_purge nonce is rendered in the admin bar on frontend pages accessible to all authenticated users including subscribers, meaning any authenticated user possesses the nonce required to trigger the deletion.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/the-cache-purger/tags/2.3.03/work/inc/kp-cache-purge-admin.php#L132","https://plugins.trac.wordpress.org/browser/the-cache-purger/tags/2.3.03/work/inc/kp-cache-purge-common.php#L223","https://plugins.trac.wordpress.org/browser/the-cache-purger/tags/2.3.03/work/inc/kp-cache-purge-common.php#L242","https://plugins.trac.wordpress.org/browser/the-cache-purger/tags/2.3.03/work/inc/kp-cache-purge-common.php#L99","https://plugins.trac.wordpress.org/changeset?reponame=&old=3603867%40the-cache-purger&new=3603867%40the-cache-purger"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-15350","score":0.00385,"percentile":0.32585,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
