This is due to insufficient file extension validation caused by a trailing-dot filename bypass, where the extension allow-list check in ajax_import_media_start() uses pathinfo() on the raw ZIP entry name (e.g., 'shell.php.'), which returns an empty string for the extension, causing the allow-list guard to be skipped and the file to be extracted to a temporary location, after which import_media_file_secure() copies it into the WordPress uploads directory without re-validating the extension. This makes it possible for authenticated attackers, with administrator-level access and above, to upload files that may be executable, which makes remote code execution possible."}], "title": "Post Export Import with Media <= 1.13.1 - Authenticated (Administrator+) Arbitrary File Upload via Trailing-Dot Filename Bypass in ZIP Media Import", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/42f94f80-6157-4778-ad69-184943134fd2?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/post-export-import-with-media/tags/1.13.1/includes/class-media-handler.php#L364"}, {"url": "https://plugins.trac.wordpress.org/browser/post-export-import-with-media/tags/1.13.1/includes/class-media-handler.php#L789"}, {"url": "https://plugins.trac.wordpress.org/browser/post-export-import-with-media/tags/1.13.1/includes/class-media-handler.php#L389"}, {"url": "https://plugins.trac.wordpress.org/browser/post-export-import-with-media/tags/1.13.1/includes/class-media-handler.php#L444"}, {"url": "https://plugins.trac.wordpress.org/browser/post-export-import-with-media/tags/1.13.1/includes/class-media-handler.php#L268"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3600506%40post-export-import-with-media&new=3600506%40post-export-import-with-media"}], "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": "Chloe Chamberland"}, {"lang": "en", "type": "finder", "value": "PRISM"}], "timeline": [{"time": "2026-07-07T15:48:54.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-09T15:21:34.000Z", "lang": "en", "value": "Disclosed"}]}}}
