Description
A Denial Of Service via File Upload (DOS) vulnerability in Liferay Portal 7.4.3.0 through 7.4.3.132, Liferay DXP 2025.Q1.0 through 2025.Q1.8, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.0 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.16 and 7.4 GA through update 92 allows a user to upload a profile picture of more than 300kb into a user profile. This size is more than the noted max 300kb size. This extra data can significantly slow down the Liferay service.

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
No patched version of com.liferay.portal:release.portal.bom has shipped for GHSA-cg99-m88x-422c yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
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-cg99-m88x-422c 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-cg99-m88x-422c. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-cg99-m88x-422c in your dependencies?
O3 detects GHSA-cg99-m88x-422c across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
