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...
