GHSA-jf24-p9p9-4rjh
HIGHGHSA-jf24-p9p9-4rjh is a high-severity (CVSS 7.5) CWE-190 vulnerability in github.com/gorilla/websocket. O3 Security confirms whether GHSA-jf24-p9p9-4rjh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Integer overflow in github.com/gorilla/websocket
Real-World Exposure
github.com/gorilla/websocketReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
An integer overflow vulnerability exists with the length of websocket frames received via a websocket connection. An attacker would use this flaw to cause a denial of service attack on an HTTP Server allowing websocket connections.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/gorilla/websocket | all versions | 1.4.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gorilla/websocket. 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/gorilla/websocket to 1.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jf24-p9p9-4rjh 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-jf24-p9p9-4rjh 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-jf24-p9p9-4rjh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is GHSA-jf24-p9p9-4rjh in your dependencies?
O3 detects GHSA-jf24-p9p9-4rjh across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
