`ftpcp()` does not use actual peer address and trusts server-supplied PASV host address (bsc#1265268).\n- CVE-2026-8643: path traversal via malicious entry point name in `pip` `wheel` installation allows arbitrary file\n  overwrite (bsc#1266669).\n- CVE-2026-11940: tarfile extraction filter bypass via a crafted archive allows escaping the destination directory and\n  enables arbitrary file reads and writes (bsc#1268977).\n- CVE-2026-11972: infinite loop due to improper EOF handling in the `tarfile` module streaming mode can lead to DoS\n  (bsc#1269788).\n- CVE-2026-15308: incremental
