CVE-2026-54591

A flaw was found in AsyncSSH, a Python package for SSHv2 protocol implementation. A malicious SSH server could exploit this vulnerability by sending specially crafted filenames containing directory traversal sequences to an AsyncSSH SCP client. This could allow the server to write arbitrary files...

CVE-2026-54590

A flaw was found in AsyncSSH, a Python package for implementing the SSHv2 protocol. An incomplete fix for a previous vulnerability allowed an attacker to bypass security restrictions in the AuthorizedKeysFile processing. By using specific characters like or environment variables $ENV in the...

CVE-2026-54591

AsyncSSH (Python) prior to 2.23.1 is vulnerable to SCP path traversal: a malicious SSH server can craft filenames with ../, since _parse_cd_args returns server-provided names verbatim and _recv_files joins them to the destination path without enforcing directory boundaries, enabling arbitrary fil...
