GHSA-mg53-xr8m-86hw
HIGHGHSA-mg53-xr8m-86hw is a high-severity (CVSS 7.5) Open Redirect vulnerability in com.liferay.portal:release.portal.bom. O3 Security confirms whether GHSA-mg53-xr8m-86hw is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Open Redirect in Liferay Portal
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 redirect module in Liferay Portal before 7.3.3 does not limit the number of URLs resulting in a 404 error that is recorded, which allows remote attackers to perform a denial of service attack by making repeated requests for pages that do not exist.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | com.liferay.portal:release.portal.bom | all versions | 7.3.3 |
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 7.3.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mg53-xr8m-86hw 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-mg53-xr8m-86hw 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-mg53-xr8m-86hw. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
