GHSA-rm43-82j9-r4mj: atomic-agents-stack Path Traversal Vulnerability
HIGHGHSA-rm43-82j9-r4mj is a HIGH path traversal vulnerability (CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) affecting atomic-agents-stack libraries in the PyPI ecosystem. The issue involves dashboard http server path traversal allows arbitrary file read. Remediation is available by upgrading affected packages to version 1.1.0.
GHSA-rm43-82j9-r4mj at a Glance
How to Fix GHSA-rm43-82j9-r4mj
To remediate this vulnerability, upgrade all affected atomic-agents-stack dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install atomic-agents-stack>=1.1.0
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show atomic-agents-stack
How to Check if You Are Affected
To determine whether your Python environment is affected by GHSA-rm43-82j9-r4mj, inspect your installed packages using pip:
pip show atomic-agents-stack
Analyze the terminal output to locate any version of atomic-agents-stack in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.
Note: The pip show atomic-agents-stack command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In atomic-agents-stack, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"summary" : "atomic-agents-stack: Dashboard HTTP server path traversal allows arbitrary file read",
"details" : "The optional dashboard HTTP server (`atomic_agents/dashboard/serve.py`) builds filesystem paths directly from the request path and serves them without a containment check. It is the only per-request untrusted-path site in the codebase that does not route through `_io.safe_resolve_under`. Literal `../` segments survive `urlparse` and `Path` joining, so a request can read files outside the intended `agents_root` (including via the static branch).\n\n**Impact:** arbitrary file read. The default bind is loopback, but `--host` is an operator-settable documented flag; binding `0.0.0.0` exposes this to the LAN. Even on loopback it is reachable via DNS-rebinding from a browser or SSRF from a co-located service.\n\n**Affected:** `dashboard/serve.py` (`DashboardHandler.do_GET` / `_serve_file`), all versions through 1.0.0.\n\n**Fix:** route every served path through `_io.safe_resolve_under` against the intended root and return 404 on `PathTraversalError`; reject `..`/separators early; optionally refuse a non-loopback `--host` unless an explicit auth/allow flag is set (matching `serve/_app.py`).",
