Real-World Exposure
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
Summary
A cross-site scripting (XSS) vulnerability has been identified in Leantime. The vulnerability allows an attacker to inject malicious scripts into certain fields, potentially leading to the execution of arbitrary code or unauthorized access to user-sensitive information. The code does not include any validation or sanitization of the $_GET["id"] parameter. As a result, it directly incorporates the user-supplied value into the source path without any checks.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for leantime/leantime, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update leantime/leantime to 3.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v4q9-437p-mhpg 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-v4q9-437p-mhpg can be triaged on real exposure rather than presence alone.
Tailored to GHSA-v4q9-437p-mhpg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
