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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-10T20:25:31.134226Z","id":"CVE-2026-13430","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":"2026-07-10T20:31:29.049Z"}}]}}
