Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Vulnerable: atomic-agents-stack versions before 1.1.0. The optional dashboard HTTP server builds file paths directly from request paths without a containment check, so a crafted request can read arbitrary files outside the intended agents root, including through the static file branch. An attacker who can reach the dashboard, over the network if it is bound to a non-loopback address or via DNS rebinding or SSRF on loopback, can read any file the server process can access. Upgrade to atomic-agents-stack 1.1.0 or later.
