CVE-2026-91989

atomic-agents-stack before 1.1.0 contains a path traversal vulnerability in the dashboard HTTP server that allows remote attackers to read arbitrary files by supplying directory traversal sequences in request paths. Attackers can bypass path containment checks by including '../' segments in requests to the DashboardHandler.do_GET endpoint to access files outside the intended agents_root directory.
