GHSA-g3mv-64h3-h482
MEDIUMGHSA-g3mv-64h3-h482 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in cockpit-hq/cockpit. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-g3mv-64h3-h482 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cockpit-hq/cockpit. 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.
Remediation status
No patched version of cockpit-hq/cockpit has shipped for GHSA-g3mv-64h3-h482 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-g3mv-64h3-h482 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-g3mv-64h3-h482. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
