GHSA-8j98-cjfr-qx3h is a high-severity (CVSS 8.1) Information Exposure vulnerability in github.com/ecies/go/v2. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-8j98-cjfr-qx3h is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
github.com/ecies/go vulnerable to possible private key restoration
Real-World Exposure
github.com/ecies/go/v2Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
If functions Encapsulate(), Decapsulate() and ECDH() could be called by an attacker, he could recover any private key that he interacts with.
Patches
Patched in v2.0.8
Workarounds
You could manually check public key by calling IsOnCurve() function from secp256k1 libraries.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ecies/go/v2. 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 github.com/ecies/go/v2 to 2.0.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8j98-cjfr-qx3h 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-8j98-cjfr-qx3h 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-8j98-cjfr-qx3h. 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-8j98-cjfr-qx3h in your dependencies?
O3 detects GHSA-8j98-cjfr-qx3h across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
