GHSA-3hfj-qcvj-4hx8
Leantime has Missing Authorization Check for Host Parameter
Blast Radius
leantime/leantimeReal-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
Finding Description
Application has functionality for a user to view profile information. It does not have an implemented authorization check for "Host" parameter which allows a user to view profile information of another user by replacing "Host" parameter.
Impact
By exploiting this vulnerability an attacker can able to view profile information (but not anything else or change anything)
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | leantime/leantime | all versions | 3.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for leantime/leantime. 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 leantime/leantime to 3.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3hfj-qcvj-4hx8 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-3hfj-qcvj-4hx8 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-3hfj-qcvj-4hx8. 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-3hfj-qcvj-4hx8 in your dependencies?
O3 detects GHSA-3hfj-qcvj-4hx8 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
