GHSA-6wj9-77wq-jq7p

HIGH

GHSA-6wj9-77wq-jq7p is a high-severity (CVSS 7.5) CWE-776 vulnerability in nokogiri. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-6wj9-77wq-jq7p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nokogiri. 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.

  2. Fix

    Update nokogiri to 1.5.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6wj9-77wq-jq7p is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-6wj9-77wq-jq7p 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-6wj9-77wq-jq7p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
