Prior to 2.1.70, the netmount command is omitted from elFinderConnector::$csrfProtectedCmds in php/elFinderConnector.class.php, so validateCsrfToken() is not called for this state-changing operation. In the shipped php/connector.minimal.php-dist configuration, FTP network mounts are enabled by default, and attacker-controlled protocol, host, path, port, user, pass, alias, and options arguments flow through elFinder::netmount() in php/elFinder.class.php to php/elFinderVolumeFTP.class.php. A cross-site request can therefore persist an attacker-chosen FTP mount in the victim's session, cause the PHP server to connect to an attacker-chosen FTP host and port, and send supplied credentials without an X-elFinder-CSRF token. This issue is fixed in version 2.1.70."}],"source":{"advisory":"GHSA-9hjf-w35w-6vx2","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/Studio-42/elFinder/security/advisories/GHSA-9hjf-w35w-6vx2","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-01T13:54:45.736717Z","id":"CVE-2026-81890","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-01T13:55:03.629Z"}}]}}
