CVE-2026-78409

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

GHSA-9HJF-W35W-6VX2 elFinder: CSRF in netmount allows forced FTP mounts and server-side FTP connections

Summary The PHP connector's CSRF gate protects many mutating commands, but it does not protect the netmount connector command. In the shipped minimal connector setup, FTP network mounting is enabled by default, so a cross-site request can force an elFinder instance to mount an attacker-chosen FTP...
