Prior to 0.3.7, `@openhop/server` passes unauthenticated flow route parameters from `GET /api/flows/:id` and `DELETE /api/flows/:id` in `packages/server/src/routes.ts` to `FlowStore.filePath()` in `packages/server/src/store.ts` without an identifier allow-list. The router applies `decodeURIComponent` to the id, and `path.join()` then normalizes traversal outside the configured flow directory after appending the .yaml extension. An attacker can read accessible YAML files as YAML-parsed JSON or permanently delete accessible .yaml files outside that directory, exposing configuration or secrets and disrupting dependent services. In `packages/server/src/index.ts`, CORS `origin: true` permits any browser origin, enabling a malicious webpage to target a loopback-bound instance. Docker deployments default to `HOST=0.0.0.0` and permit direct unauthenticated network access. This issue is fixed in repository release 0.3.7.","state":0,"publishedAt":"2026-10-28T14:17:04.907+00:00","modifiedAt":"2026-10-28T15:24:56.033+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:H","score":8.3,"severity":"HIGH"}],"references":["https://github.com/naorsabag/openhop/commit/c8190fbefa3a50e7b0c16c001d2e05b0e920cfb4","https://github.com/naorsabag/openhop/pull/190","https://github.com/naorsabag/openhop/releases/tag/v0.3.7","https://github.com/naorsabag/openhop/security/advisories/GHSA-g72f-jw3w-mgh7"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-59179","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22"],"productCriteria":[],"sourceDates":{"published":"2026-10-28T14:17:04.907","lastModified":"2026-10-28T15:24:56.033"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
