The records we use list no patched version of com.liferay.portal:release.portal.bom for GHSA-m49p-6cjp-x2h3. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

How do I detect GHSA-m49p-6cjp-x2h3 in my Maven dependencies?

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

How do I mitigate GHSA-m49p-6cjp-x2h3 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-m49p-6cjp-x2h3 actively exploited in the wild?

No public exploit code has been indexed for GHSA-m49p-6cjp-x2h3 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-m49p-6cjp-x2h3?

GHSA-m49p-6cjp-x2h3 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 8th 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-m49p-6cjp-x2h3?

Description

A stored DOM-based Cross-Site Scripting (XSS) vulnerability in Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.5, 2025.Q1.0 through 2025.Q1.15, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.19 and 7.4 GA through update 92 exists in the Asset Publisher configuration UI within the Source.js module. This vulnerability allows attackers to inject arbitrary JavaScript via DDM structure field labels which are then inserted into the DOM using innerHTML without proper encoding.
