This is due to missing file extension, MIME type, and size validation in the signature field's validation_filter(), combined with the absence of PHP-execution guards in the upload directory and a sanitize_file_name() bypass that converts shell.php- into shell.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible."}],"title":"Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) <= 3.4.5 - Unauthenticated Arbitrary File Upload via Signature Field File Upload","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/fa3193c4-dd3e-4d9e-be42-769c7358beae?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/includes/class.form-data-store.php#L42"},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/admin/include/class.cf7-signature.php#L222"},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/admin/include/class.cf7-signature.php#L82"},{"url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/includes/class.cf7-extensions.php#L289"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3727009%40extensions-for-cf7%2Ftags%2F3.4.6&old=3672142%40extensions-for-cf7%2Ftags%2F3.4.5"},{"url":"https://plugins.trac.wordpress.org/changeset/3727009/extensions-for-cf7/trunk/admin/include/class.cf7-signature.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:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Osman Hussein"}],"timeline":[{"time":"2026-09-21T21:12:37.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-09T15:24:50.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-94589","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-11T16:43:32.558627Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-11T16:55:19.810Z"}}]}}
