CVE-2026-119364 · Severity: medium · CVSS 5.3 · Published 2026-10-30

ProFTPD is a widely-used FTP server that manages file transfers. An authenticated attacker can exploit a flaw in the SITE COPY command to bypass write restrictions by placing symlinks in writable directories, potentially overwriting sensitive files on the server. This allows an authenticated FTP user to modify files they should not have access to.
