Update com.liferay:com.liferay.calendar.web to 5.0.87 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gj92-p9mh-83j8 is resolved across your whole dependency graph.

How do I detect GHSA-gj92-p9mh-83j8 in my Maven dependencies?

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

How do I mitigate GHSA-gj92-p9mh-83j8 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-gj92-p9mh-83j8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-gj92-p9mh-83j8 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-gj92-p9mh-83j8?

GHSA-gj92-p9mh-83j8 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 14th 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-gj92-p9mh-83j8?
