GHSA-xvgg-9h29-4g34 affects the following packages: com.liferay.portal:com.liferay.portal.impl (Maven), com.liferay.portal:com.liferay.portal.kernel (Maven). Ecosystems affected: Maven.

How do I fix GHSA-xvgg-9h29-4g34?

Update com.liferay.portal:com.liferay.portal.impl to 96.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xvgg-9h29-4g34 is resolved across your whole dependency graph.

How do I detect GHSA-xvgg-9h29-4g34 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-xvgg-9h29-4g34 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-xvgg-9h29-4g34?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-xvgg-9h29-4g34 can be triaged on real exposure rather than presence alone.

Is GHSA-xvgg-9h29-4g34 actively exploited in the wild?

No public exploit code has been indexed for GHSA-xvgg-9h29-4g34 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-xvgg-9h29-4g34?

GHSA-xvgg-9h29-4g34 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 35th 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-xvgg-9h29-4g34?

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Liferay Portal 7.4.0 through 7.4.3.105, and older unsupported versions, and Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions may incorrectly identify the subdomain of a domain name and create a supercookie, which allows remote attackers who control a website that share the same TLD to read cookies set by the application.
