Description
In Liferay Impl before 5.18.4, Liferay Users Admin Web before 5.0.33, Liferay Login Web before 5.0.18, and Liferay Commerce Account Web before 3.0.7 from Liferay Portal (7.2.0 through 7.3.5), and older unsupported versions, and Liferay DXP 7.3 before fix pack 1, 7.2 before fix pack 17, and older unsupported versions does not obfuscate password reminder answers on the page, which allows attackers to use man-in-the-middle or shoulder surfing attacks to steal user's password reminder answers.

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:portal-impl. 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:portal-impl to 5.18.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mwhf-6mjm-6w3h 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-mwhf-6mjm-6w3h 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-mwhf-6mjm-6w3h. 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-mwhf-6mjm-6w3h in your dependencies?
O3 detects GHSA-mwhf-6mjm-6w3h across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
