GHSA-mg85-8mv5-ffjr
GHSA-mg85-8mv5-ffjr is a security vulnerability in ammo. O3 Security confirms whether GHSA-mg85-8mv5-ffjr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial of Service in ammo
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.
ammonpmDescription
All versions of ammo are vulnerable to Denial of Service. The Range HTTP header parser has a vulnerability which will cause the function to throw a system error if the header is set to an invalid value. Because hapi is not expecting the function to ever throw, the error is thrown all the way up the stack. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.
Recommendation
This package is deprecated and is now maintained as @hapi/ammo. Please update your dependencies to use @hapi/ammo.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ammo. 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.
Remediation status
No patched version of ammo has shipped for GHSA-mg85-8mv5-ffjr yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-mg85-8mv5-ffjr 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-mg85-8mv5-ffjr. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-mg85-8mv5-ffjr in your dependencies?
O3 detects GHSA-mg85-8mv5-ffjr across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
