{"id":"CVE-2026-15350","state":"PUBLISHED","title":"The Cache Purger <= 2.3.20 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Log Deletion via 'the_log_purge' Parameter","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.","publishedAt":"2026-07-16T07:51:01.300Z","updatedAt":"2026-07-16T13:44:37.970Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["kevp75 The Cache Purger"],"affected":[{"vendor":"kevp75","product":"The Cache Purger","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.3.20","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5a9943b5-0f6d-4fbd-97eb-df61acd0c297?source=cve","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#L223","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/browser/the-cache-purger/tags/2.3.03/work/inc/kp-cache-purge-admin.php#L132","https://plugins.trac.wordpress.org/changeset?reponame=&old=3603867%40the-cache-purger&new=3603867%40the-cache-purger"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15350.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15350","state":"PUBLISHED","datePublished":"2026-07-16T07:51:01.300Z","dateUpdated":"2026-07-16T13:44:37.970Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-09T20:41:30.861Z"},"containers":{"cna":{"title":"The Cache Purger <= 2.3.20 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Log Deletion via 'the_log_purge' Parameter","descriptions":[{"lang":"en","value":"The The Cache Purger plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.20.
