LoopX Permissive CORS Policy Vulnerability

Sources read

Source agreement

Tam uyum

Evidence confidence

Short explanation

The overly permissive CORS policy in the loopx serve-status component of LoopX versions 0.0.1 through 0.4.5 allows remote attackers to access sensitive control plane data and private Markdown files without authentication.

Why does it matter?

This vulnerability exposes control-plane state, local absolute paths, and private Markdown files if an operator visits attacker-controlled web content.

What should be done?

Update the software or follow the vendor advisory

Show the technical text from the sources

Open and provider-neutral, LoopX is a lightweight state kernel and local-first control plane for loop engineering. From version 0.0.1 until 0.4.5, `loopx serve-status` in `loopx/status_server.py` uses `StatusRequestHandler._send_json()` and `do_OPTIONS()` to send `Access-Control-Allow-Origin: *` for unauthenticated responses on predictable loopback ports. A remote attacker can cause an operator who visits attacker-controlled web content to issue cross-origin requests to `GET /status.json`, `GET /review-material?goal_id=...&path=...`, `GET /`, and `POST /control-plane/configure-goal/dry-run`, exposing control-plane state, goal and run information, local absolute paths, private Markdown files below registered goal roots, and dry-run configuration projections. The affected routes do not provide cross-origin writes or arbitrary-file access. This issue is fixed in version 0.4.5.
