This makes it possible for authenticated attackers, with Editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The attacker can upload a benign image file, then use the `update_media_metadata` endpoint to rename it to a PHP file, creating an executable PHP file in the uploads directory."}],"title":"AI Engine <= 3.3.2 - Authenticated (Editor+) Arbitrary File Upload via 'filename' Parameter in update_media_metadata Endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/d5227269-4406-4fcf-af37-f1db0af857d6?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.3.0/classes/rest.php#L1104"},{"url":"https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.3.0/classes/rest.php#L1141"},{"url":"https://plugins.trac.wordpress.org/changeset/3447500/ai-engine/trunk/classes/rest.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":7.2,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"M Indra Purnama"}],"timeline":[{"time":"2026-01-23T21:59:21.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-01-27T19:28:10.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-01-28T16:06:48.366374Z","id":"CVE-2026-1400","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-01-28T16:06:59.438Z"}}]}}
