{"id":"CVE-2026-15991","state":"PUBLISHED","title":"File Manager 6.0 - 6.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary File Read and Deletion via 'cmd' Query Parameter","description":"The File Manager plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the connector function in all versions from 6.0 - 6.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to read and delete arbitrary files on the server, which can lead to remote code execution when the right file is deleted (such as wp-config.php). The bypass is triggered by passing cmd=rm or cmf=file in the URL query string of a POST request: elFinder's bind registration reads the command exclusively from $_POST and therefore never registers the rm.pre permission handler, while the dispatcher reads from the merged $_GET+$_POST superglobal and executes the rm or file command unchecked against a volume that defaults to ABSPATH.","publishedAt":"2026-08-06T03:26:08.422Z","updatedAt":"2026-08-06T15:37:22.456Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["bitpressadmin File Manager"],"affected":[{"vendor":"bitpressadmin","product":"File Manager","defaultStatus":"unaffected","versions":[{"version":"6.0","status":"affected","lessThanOrEqual":"6.9","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a041f15c-0e30-459b-8df7-0465c0bc268a?source=cve","https://plugins.trac.wordpress.org/browser/file-manager/tags/6.9/backend/app/Http/Controllers/FileManagerController.php#L34","https://plugins.trac.wordpress.org/browser/file-manager/tags/6.9/vendor/studio-42/elfinder/php/elFinder.class.php#L802","https://plugins.trac.wordpress.org/browser/file-manager/tags/6.9/vendor/studio-42/elfinder/php/elFinderConnector.class.php#L320","https://plugins.trac.wordpress.org/browser/file-manager/tags/6.9/backend/app/Http/Controllers/FileManagerController.php#L32","https://plugins.trac.wordpress.org/browser/file-manager/tags/6.9/backend/app/Providers/AccessControlProvider.php#L121","https://plugins.trac.wordpress.org/browser/file-manager/tags/6.9/backend/hooks/ajax.php#L10","https://plugins.trac.wordpress.org/changeset?old_path=%2Ffile-manager/tags/6.9&new_path=%2Ffile-manager/tags/6.9.1","https://plugins.trac.wordpress.org/changeset/3632660/file-manager/trunk/backend/app/Http/Controllers/FileManagerController.php"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15991.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15991","state":"PUBLISHED","datePublished":"2026-08-06T03:26:08.422Z","dateUpdated":"2026-08-06T15:37:22.456Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-16T20:10:30.067Z"},"containers":{"cna":{"title":"File Manager 6.0 - 6.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary File Read and Deletion via 'cmd' Query Parameter","descriptions":[{"lang":"en","value":"The File Manager plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the connector function in all versions from 6.0 - 6.9.
