The plugin caches the response of Core’s wp-activate.php without honoring its no-store/no-cache headers, the wp-activate-* cookie, or the WP_INSTALLING state, writing the credential-bearing activation response to a publicly accessible cache file. This makes it possible for unauthenticated attackers to retrieve the plaintext username and twelve-character password of the most recently activated Multisite registrant from that cached wp-activate.php response. Exploitation requires a Multisite subdirectory installation with public user and site registration enabled, and the credentials are only exposed after a genuine registrant follows their activation link.","score":5.9,"severity":"medium","published":"2026-11-03T02:31:19.933Z","modified":"2026-11-03T13:23:51.631Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"emrevona","name":"WP Fastest Cache – WordPress Cache Plugin","platforms":[],"versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.5.3","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"Wordfence","url":"https://www.cve.org/CVERecord?id=CVE-2026-111464"}],"remediation":[],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/83539a88-b90e-49f0-a599-b3f83b2d97b9?source=cve","https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L1027","https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L452","https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L567","https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L1400","https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L83","https://plugins.trac.wordpress.org/changeset/3749897/wp-fastest-cache"],"sources":[{"name":"CVE","id":"CVE-2026-111464","modified":"2026-11-03T13:23:51.631Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-111464"}],"assessments":[{"source":"Wordfence","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9}],"sourceAffected":[],"observedAt":"2026-11-03T13:30:41.835Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T02:45:32.518Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-11-03T02:45:31.344Z","attemptedAt":"2026-11-03T02:45:31.344Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-03T02:45:31.344Z","attemptedAt":"2026-11-03T02:45:31.344Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-11-03T02:45:31.344Z","attemptedAt":"2026-11-03T02:45:31.344Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-03T02:45:31.344Z","attemptedAt":"2026-11-03T02:45:31.344Z"}],"evidence":[],"aiSummary":{"text":"WP Fastest Cache plugin versions up to 1.5.3 are vulnerable to sensitive information exposure.
