GHSA-c429-5p7v-vgjp
HIGHGHSA-c429-5p7v-vgjp is a high-severity (CVSS 8.1) CWE-1321 vulnerability in @hapi/hoek. O3 Security confirms whether GHSA-c429-5p7v-vgjp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
hoek subject to prototype pollution via the clone function.

@hapi/hoeknpmhoeknpmDescription
hoek versions prior to 8.5.1, and 9.x prior to 9.0.3 are vulnerable to prototype pollution in the clone function. If an object with the proto key is passed to clone() the key is converted to a prototype. This issue has been patched in version 9.0.3, and backported to 8.5.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @hapi/hoek. 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 @hapi/hoek to 8.5.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c429-5p7v-vgjp 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 GHSA-c429-5p7v-vgjp 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 GHSA-c429-5p7v-vgjp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
