{"cve":"CVE-2026-15991","nvd":{"published":"2026-08-06T05:16:38.930","modified":"2026-08-12T21:00:52.257","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-862"],"references":["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/Http/Controllers/FileManagerController.php#L34","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/browser/file-manager/tags/6.9/vendor/studio-42/elfinder/php/elFinder.class.php#L802"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-15991","score":0.01072,"percentile":0.64899,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
