CVE-2026-119147

ProFTPD before 1.3.9e and 1.3.10rc5 contains an authorization bypass in the mod_sftp copy-file extension handler that skips Limit WRITE checks for new destination files. Authenticated SFTP users can copy any readable file to a new path in write-denied directories, creating files where uploads are forbidden.
