No CVSS score has been assigned to GHSA-r45v-2289-jgr4 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-r45v-2289-jgr4?

GHSA-r45v-2289-jgr4 affects the following packages: com.liferay.portal:com.liferay.portal.impl (Maven). Ecosystems affected: Maven.

How do I fix GHSA-r45v-2289-jgr4?

Update com.liferay.portal:com.liferay.portal.impl to 99.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r45v-2289-jgr4 is resolved across your whole dependency graph.

How do I detect GHSA-r45v-2289-jgr4 in my Maven dependencies?

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

How do I mitigate GHSA-r45v-2289-jgr4 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-r45v-2289-jgr4 actively exploited in the wild?

No public exploit code has been indexed for GHSA-r45v-2289-jgr4 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-r45v-2289-jgr4?

GHSA-r45v-2289-jgr4 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-r45v-2289-jgr4?

GHSA-r45v-2289-jgr4 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-r45v-2289-jgr4 published, and has it been updated?

GHSA-r45v-2289-jgr4 was published on September 15, 2025 and was last updated on December 20, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
