CVE-2026-91989Network attack vectorHinoki check available

Arbitrary file read via uncontained dashboard paths

Published Sep 15, 2026 · Updated Sep 15, 2026

Path traversal in dep0we atomic-agents-stack 1.0.0 and earlier allows remote attackers to read arbitrary files through dashboard requests. DashboardHandler.do_GET and _serve_file join literal ../ segments from the request path to agents_root and serve the result without safe_resolve_under containment. The optional server binds to loopback by default, but LAN exposure, DNS rebinding, or co-located SSRF permits unauthenticated reads with the server process's file permissions.
