GHSA-87m3-6qj3-p3xh is a medium-severity (CVSS 6.5) CWE-770 vulnerability in com.liferay.portal:release.portal.bom. O3 Security confirms whether GHSA-87m3-6qj3-p3xh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Liferay Portal denial of service (memory consumption)
Real-World Exposure
com.liferay.portal:release.portal.bomReal-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
The Document and Media widget In Liferay Portal 7.2.0 through 7.3.6, and older unsupported versions, and Liferay DXP 7.3 before service pack 3, 7.2 before fix pack 13, and older unsupported versions, does not limit resource consumption when generating a preview image, which allows remote authenticated users to cause a denial of service (memory consumption) via crafted PNG images.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | com.liferay.portal:release.portal.bom | ≥ 7.2.0&&< 7.3.7 | 7.3.7 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay.portal:release.portal.bom. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update com.liferay.portal:release.portal.bom to 7.3.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-87m3-6qj3-p3xh is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-87m3-6qj3-p3xh is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-87m3-6qj3-p3xh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
