A flaw was found in the FTP GVfs backend. A remote attacker could exploit this input validation vulnerability by supplying specially crafted file paths containing carriage return and line feed (CRLF) sequences. These unsanitized sequences allow the attacker to terminate intended FTP commands and inject arbitrary FTP commands, potentially leading to arbitrary code execution or other severe impacts.

The version of gvfs installed on the remote host is prior to 1.36.2-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3197 advisory.

    A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by     providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally     trusts this information and attempts to connect to the specified endpoint, allowing the malicious server     to probe for open ports accessible from the client's network.
