Description
CVE-2026-119147 is an authorization bypass vulnerability in ProFTPD versions before 1.3.9e and 1.3.10rc5. It affects the mod_sftp copy-file extension handler, allowing authenticated SFTP users to copy readable files to new locations in directories where write permissions are denied. This bypasses the intended Limit WRITE restrictions, enabling unauthorized file creation in protected directories.
