CVE-2026-81891: CWE-434: Unrestricted Upload of File with Dangerous Type in Studio-42 elFinderCVE-2026-81891 0 elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.70, checkExtractItems() in php/elFinderVolumeDriver.class.php calls mimetypeInternalDetect() without passing the result through mimeTypeNormalize(). Because the .phtml, .phar, .php5, and .php3 extensions are absent from mime.types, the staticMimeMap entries that map them to text/x-php are not applied, and allowPutMime() permits extraction even when uploadDeny blocks text/x-php. An attacker with ZIP upload permission can extract PHP-executable files into a web-accessible files/ directory and achieve remote code execution when the server executes those extensions. This issue is fixed in version 2.1.70. Join the discussion | CVE Database V5 | 08/31/2026, 20:33:22 UTC Added: 08/31/2026, 20:53:04 UTC |
