CVE-2026-25141
CVE-2026-25141 is a Code Injection vulnerability in @orval/core. O3 Security confirms whether CVE-2026-25141 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Orval has a code injection via unsanitized x-enum-descriptions uing JS comments
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
@orval/corenpmDescription
Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Versions starting with 7.19.0 and prior to 7.21.0 and 8.2.0 have an incomplete fix for CVE-2026-23947. While the jsStringEscape function properly handles single quotes ('), double quotes (") and so on, it is still possible to achieve code injection using only a limited set of characters that are currently not escaped. The vulnerability lies in the fact that the application can be forced to execute arbitrary JavaScript using characters such as !+. By using a technique known as JSFuck, an attacker can bypass the current sanitization logic and run arbitrary code without needing any alphanumeric characters or quotes. Version 7.21.0 and 8.2.0 contain an updated fix.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @orval/core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update @orval/core to 7.21.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-25141 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-25141 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-25141. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
