GHSA-c8x3-rg72-fwwg
HIGHGHSA-c8x3-rg72-fwwg is a high-severity (CVSS 8.8) CWE-295 vulnerability in github.com/hashicorp/nomad. O3 Security confirms whether GHSA-c8x3-rg72-fwwg is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-c8x3-rg72-fwwg plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 365,017 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
HashiCorp Nomad and Nomad Enterprise Raft RPC layer allows non-server agents with a valid certificate signed by the same CA to access server-only functionality, enabling privilege escalation. Fixed in 1.0.10 and 1.1.4.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/hashicorp/nomad | all versions | 1.0.10 |
| 🐹Go | github.com/hashicorp/nomad | ≥ 1.1.0&&< 1.1.4 | 1.1.4 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/hashicorp/nomad. 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/hashicorp/nomad to 1.0.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c8x3-rg72-fwwg 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-c8x3-rg72-fwwg 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-c8x3-rg72-fwwg. 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-c8x3-rg72-fwwg in your dependencies?
O3 detects GHSA-c8x3-rg72-fwwg across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
