GHSA-c39w-3pjx-qc7m is a security vulnerability in leantime/leantime. A fix is available for leantime/leantime — see the affected versions and patch details below.
Leantime allows Stored Cross-Site Scripting (XSS)
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
Description
Leantime allows stored cross-site scripting (XSS) in the API key name while generating the API key.
Impact
Any low privileged user like manager, or editor, can create an API key with XSS payload. When admin will visit the Company page, the XSS will automatically get triggerred leading to the unauthorized action performed from the ADMIN account. Like, removing any user, or adding someone else as high privilege, and many more.

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-c39w-3pjx-qc7m 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-c39w-3pjx-qc7m can be triaged on real exposure rather than presence alone.
Tailored to GHSA-c39w-3pjx-qc7m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
