No CVSS score has been assigned to GHSA-6pgj-w687-9c8c yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-6pgj-w687-9c8c?

GHSA-6pgj-w687-9c8c affects the following packages: com.liferay:com.liferay.portal.cluster.multiple (Maven). Ecosystems affected: Maven.

How do I fix GHSA-6pgj-w687-9c8c?

Update com.liferay:com.liferay.portal.cluster.multiple to 5.0.35 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6pgj-w687-9c8c is resolved across your whole dependency graph.

How do I detect GHSA-6pgj-w687-9c8c in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.portal.cluster.multiple, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-6pgj-w687-9c8c 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-6pgj-w687-9c8c?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-6pgj-w687-9c8c can be triaged on real exposure rather than presence alone.

Is GHSA-6pgj-w687-9c8c actively exploited in the wild?

No public exploit code has been indexed for GHSA-6pgj-w687-9c8c 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-6pgj-w687-9c8c?

GHSA-6pgj-w687-9c8c has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 6th 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.

What type of vulnerability is GHSA-6pgj-w687-9c8c?

GHSA-6pgj-w687-9c8c is classified as CWE-346 (CWE-346). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.
