GHSA-r9p9-mrjm-926w
MEDIUMGHSA-r9p9-mrjm-926w is a medium-severity (CVSS 6.8) Broken Cryptographic Algorithm vulnerability in elliptic. O3 Security confirms whether GHSA-r9p9-mrjm-926w is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
ellipticnpmDescription
The npm package elliptic before version 6.5.4 are vulnerable to Cryptographic Issues via the secp256k1 implementation in elliptic/ec/key.js. There is no check to confirm that the public key point passed into the derive function actually exists on the secp256k1 curve. This results in the potential for the private key used in this implementation to be revealed after a number of ECDH operations are performed.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for elliptic. 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 elliptic to 6.5.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r9p9-mrjm-926w 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-r9p9-mrjm-926w 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-r9p9-mrjm-926w. 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-r9p9-mrjm-926w in your dependencies?
O3 detects GHSA-r9p9-mrjm-926w across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
