CVE-2026-45309: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in ronf asyncsshCVE-2026-45309 0 AsyncSSH is a Python package which provides an asynchronous client and server implementation of the SSHv2 protocol on top of the Python asyncio framework. Prior to 2.23.0, AsyncSSH expands the OpenSSH-compatible AuthorizedKeysFile %u token in asyncssh/config.py, asyncssh/connection.py, asyncssh/auth_keys.py, and asyncssh/misc.py with the raw SSH username during pre-authentication server config reload, allowing a server configured with AuthorizedKeysFile authorized_keys/%u to read an authorized-keys file outside the intended directory when the SSH username contains /, \, or .. path traversal segments and authenticate with an attacker-selected key file. This issue is fixed in version 2.23.0. Join the discussion | CVE Database V5 | 07/17/2026, 18:40:02 UTC Added: 07/18/2026, 11:08:35 UTC |
