GHSA-hqwm-7x7x-8379
HIGHGHSA-hqwm-7x7x-8379 is a high-severity (CVSS 7.7) vulnerability in github.com/loft-sh/devspace. O3 Security confirms whether GHSA-hqwm-7x7x-8379 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Description
DevSpace's UI server WebSocket accepts connections from all origins by default, and therefore several endpoints are exposed via this WebSocket. When a developer runs the DevSpace UI and at the same time uses a browser to access the internet, a malicious website they visit can use their browser to establish a cross-origin WebSocket connection to ws://127.0.0.1:8090. This allows an attacker to access:

Patches
Versions 6.3.21 and above are patched.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/loft-sh/devspace. 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/loft-sh/devspace to 6.3.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hqwm-7x7x-8379 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-hqwm-7x7x-8379 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-hqwm-7x7x-8379. 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-hqwm-7x7x-8379 in your dependencies?
O3 detects GHSA-hqwm-7x7x-8379 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
