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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"naorsabag","product":"openhop","versions":[{"version":"< 0.3.7","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:H","baseScore":8.3,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.5}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-22"}]}],"references":[{"url":"https://github.com/naorsabag/openhop/commit/c8190fbefa3a50e7b0c16c001d2e05b0e920cfb4","source":"security-advisories@github.com"},{"url":"https://github.com/naorsabag/openhop/pull/190","source":"security-advisories@github.com"},{"url":"https://github.com/naorsabag/openhop/releases/tag/v0.3.7","source":"security-advisories@github.com"},{"url":"https://github.com/naorsabag/openhop/security/advisories/GHSA-g72f-jw3w-mgh7","source":"security-advisories@github.com"}]}
