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."}],"title":"WP Fastest Cache <= 1.5.3 - Unauthenticated Sensitive Information Exposure via Cached wp-activate.php Response","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/83539a88-b90e-49f0-a599-b3f83b2d97b9?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L1027"},{"url":"https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L452"},{"url":"https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L567"},{"url":"https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L1400"},{"url":"https://plugins.trac.wordpress.org/browser/wp-fastest-cache/tags/1.5.2/inc/cache.php#L83"},{"url":"https://plugins.trac.wordpress.org/changeset/3749897/wp-fastest-cache"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-524 Use of Cache Containing Sensitive Information","cweId":"CWE-524","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":5.9,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"R3D"}],"timeline":[{"time":"2026-10-16T06:14:47.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-11-02T13:45:57.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-11-03T13:23:01.915368Z","id":"CVE-2026-111464","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-11-03T13:23:51.631Z"}}]}}
