CVE-2024-56361
Fix: tltneon/lgsl@3fbd3bbCVE-2024-56361 is a Cross-site Scripting (XSS) vulnerability in tltneon/lgsl. O3 Security confirms whether CVE-2024-56361 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Stored Cross-Site Scripting (XSS) in lgsl v7.0
Real-World Exposure
tltneon/lgslReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
LGSL (Live Game Server List) provides online status for games. Before 7.0.0, a stored cross-site scripting (XSS) vulnerability was identified in lgsl. The function lgsl_query_40 in lgsl_protocol.php has implemented an HTTP crawler. This function makes a request to the registered game server, and upon crawling the malicious /info endpoint with our payload, will render our javascript on the info page. This information is being displayed via lgsl_details.php. This vulnerability is fixed in 7.0.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tltneon/lgsl. 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 tltneon/lgsl to 7.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-56361 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 CVE-2024-56361 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 CVE-2024-56361. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-56361 in your dependencies?
O3 detects CVE-2024-56361 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
