{"cve":"CVE-2026-108372","nvd":{"published":"2026-10-16T22:17:14.457","modified":"2026-10-21T22:16:46.707","status":"Deferred","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-346","CWE-942"],"references":["https://github.com/loopx-project/loopx/commit/838720fba42bd22f71b5bb763ec406f7bdf4c940","https://github.com/loopx-project/loopx/pull/3137","https://github.com/loopx-project/loopx/releases/tag/v0.4.5","https://github.com/loopx-project/loopx/security/advisories/GHSA-vx2m-gpq4-8j5q","https://github.com/loopx-project/loopx/security/advisories/GHSA-vx2m-gpq4-8j5q"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-108372","score":0.00304,"percentile":0.22962,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vx2m-gpq4-8j5q","url":"https://osv.dev/vulnerability/GHSA-vx2m-gpq4-8j5q","summary":"LoopX serve-status permissive CORS policy exposes control-plane state and private Markdown files","modified":"2026-10-19T16:15:43.737645560Z","packages":[{"ecosystem":"PyPI","name":"loopx","purl":"pkg:pypi/loopx","ranges":[">=0.0.1 <0.4.5"],"fixed":["0.4.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
