CVE-2026-54590: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in ronf asyncsshCVE-2026-54590 0 AsyncSSH version 2.23.0 contains a path traversal vulnerability in the SSHServerConfig._set_tokens function. The vulnerability arises because the fix for a previous issue (CVE-2026-45309) is incomplete: it blocks certain characters before %u substitution in AuthorizedKeysFile but does not block leading ~ or ${ENV}, allowing expansion that can escape the intended authorized-keys directory. This issue is resolved in version 2.23.1. Join the discussion | CVE Database V5 | 07/08/2026, 20:36:45 UTC Added: 07/08/2026, 20:44:00 UTC |
