The `upload_extension_files()` function hooks into WordPress's `wp_check_filetype_and_ext` filter and uses `strpos()` to check if a filename contains a configured extension string, rather than verifying the actual file extension. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files (including PHP) on the affected site's server which may make remote code execution possible, granted the \"Enhanced Multi-Format Image Support\" feature is enabled with at least one extension (e.g., avif) in the allowed formats."}],"title":"Swiss Toolkit For WP <= 1.4.6 - Authenticated (Author+) Arbitrary File Upload via upload_extension_files()","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/06bccd2e-6891-433a-9f5b-3ec0c30afef4?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/swiss-toolkit-for-wp/tags/1.4.2/includes/plugins/class-boomdevs-swiss-toolkit-extension-supports.php#L95"},{"url":"https://plugins.trac.wordpress.org/browser/swiss-toolkit-for-wp/tags/1.4.2/includes/plugins/class-boomdevs-swiss-toolkit-extension-supports.php#L49"},{"url":"https://plugins.trac.wordpress.org/browser/swiss-toolkit-for-wp/trunk/includes/plugins/class-boomdevs-swiss-toolkit-extension-supports.php#L95"},{"url":"https://plugins.trac.wordpress.org/browser/swiss-toolkit-for-wp/trunk/includes/plugins/class-boomdevs-swiss-toolkit-extension-supports.php#L49"}],"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:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Williwollo (CybrX)"}],"timeline":[{"time":"2026-07-10T15:27:04.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-13T14:35:50.481926Z","id":"CVE-2026-2354","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":"2026-07-13T14:39:51.179Z"}}]}}
