FTP command injection via unsanitized CRLF paths
Published Feb 26, 2026 · Updated Feb 26, 2026
CRLF injection in the FTP GVfs backend in Red Hat Enterprise Linux 6 through 10 allows remote attackers to inject FTP commands via crafted paths. g_vfs_ftp_file_new_from_gvfs() copies a path without validation, and g_string_append_vprintf() places it directly into an FTP command buffer, where embedded CRLF terminates the intended command. Exploitation requires user interaction with attacker-controlled FTP content and is bounded to disclosure through commands issued with the victim's FTP session privileges.
