{"id":"CVE-2026-108372","summary":"LoopX serve-status permissive CORS policy exposes control-plane state and private Markdown files","details":"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.","aliases":["GHSA-vx2m-gpq4-8j5q"],"modified":"2026-10-17T10:47:16.096558086Z","published":"2026-10-16T21:29:13.757Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108372.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-346","CWE-942"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108372.json"},{"type":"FIX","url":"https://github.com/loopx-project/loopx/commit/838720fba42bd22f71b5bb763ec406f7bdf4c940"},{"type":"FIX","url":"https://github.com/loopx-project/loopx/pull/3137"},{"type":"WEB","url":"https://github.com/loopx-project/loopx/releases/tag/v0.4.5"},{"type":"ADVISORY","url":"https://github.com/loopx-project/loopx/security/advisories/GHSA-vx2m-gpq4-8j5q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-108372"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/loopx-project/loopx","events":[{"introduced":"0"},{"fixed":"80877982216577174e3e7c7cca9804c5a3a3148b"}],"database_specific":{"extracted_events":[{"introduced":"0.0.1"},{"fixed":"0.4.5"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.4.4","v0.4.3","v0.4.1","v0.4.0","v0.3.0","v0.2.13","v0.2.12","v0.2.11","v0.2.10","v0.2.9","v0.2.8","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.16","v0.1.15","v0.1.14","v0.1.13","v0.1.12","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-108372.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
