Which packages are affected by GHSA-23w4-rpc6-wpcc?

GHSA-23w4-rpc6-wpcc affects the following packages: com.liferay:com.liferay.portal.workflow.kaleo.designer.web (Maven). Ecosystems affected: Maven.

How do I fix GHSA-23w4-rpc6-wpcc?

Update com.liferay:com.liferay.portal.workflow.kaleo.designer.web to 5.0.145 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-23w4-rpc6-wpcc is resolved across your whole dependency graph.

How do I detect GHSA-23w4-rpc6-wpcc in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.portal.workflow.kaleo.designer.web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-23w4-rpc6-wpcc if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-23w4-rpc6-wpcc actively exploited in the wild?

No public exploit code has been indexed for GHSA-23w4-rpc6-wpcc 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.

Description

Self-ReDoS (Regular expression Denial of Service) exists with Role Name search field of Kaleo Designer portlet JavaScript in Liferay Portal 7.4.0 through 7.4.3.131, and Liferay DXP 2024.Q4.0 through 2024.Q4.1, 2024.Q3.0 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.20 and 7.4 GA through update 92, which allows authenticated users with permissions to update Kaleo Workflows to enter a malicious Regex pattern causing their browser to hang for a very long time.

Detection & mitigation playbook

Open-source dependency

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.portal.workflow.kaleo.designer.web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.liferay:com.liferay.portal.workflow.kaleo.designer.web to 5.0.145 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-23w4-rpc6-wpcc is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
