GHSA-wmrx-57hm-mw7r is a high-severity (CVSS 7.5) vulnerability in github.com/hashicorp/nomad. O3 Security confirms whether GHSA-wmrx-57hm-mw7r is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Arbitrary file reads in HashiCorp Nomad
Real-World Exposure

Description
Nomad is an easy-to-use, flexible, and performant workload orchestrator that can deploy a mix of microservice, batch, containerized, and non-containerized applications. HashiCorp Nomad and Nomad Enterprise 0.9.2 through 1.0.17, 1.1.11, and 1.2.5 allow operators with read-fs and alloc-exec (or job-submit) capabilities to read arbitrary files on the host filesystem as root. There are currently no known workarounds. Users are recommended to upgrade as soon as possible to avoid this issue.

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 1.0.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wmrx-57hm-mw7r 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-wmrx-57hm-mw7r 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-wmrx-57hm-mw7r. 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-wmrx-57hm-mw7r in your dependencies?
O3 detects GHSA-wmrx-57hm-mw7r across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
