How severe is GHSA-95j3-435g-vjcp?

GHSA-95j3-435g-vjcp has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-95j3-435g-vjcp?

GHSA-95j3-435g-vjcp affects the following packages: leantime/leantime (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-95j3-435g-vjcp?

Update leantime/leantime to 3.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-95j3-435g-vjcp is resolved across your whole dependency graph.

How do I detect GHSA-95j3-435g-vjcp in my Packagist dependencies?

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.

How do I mitigate GHSA-95j3-435g-vjcp if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-95j3-435g-vjcp?

O3 pinpoints whether GHSA-95j3-435g-vjcp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-95j3-435g-vjcp actively exploited in the wild?

No public exploit code has been indexed for GHSA-95j3-435g-vjcp yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-95j3-435g-vjcp?

GHSA-95j3-435g-vjcp has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 19th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-95j3-435g-vjcp published, and has it been updated?

GHSA-95j3-435g-vjcp was published on February 21, 2025 and was last updated on March 31, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
