## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Liferay Portal's com.liferay.portal.workflow.kaleo.designer.web package, versions before 5.0.145, is vulnerable to a regular expression denial of service in the Role Name search field of the Kaleo Designer portlet. An authenticated user with permission to update Kaleo Workflows can enter a crafted regex pattern that makes their own browser hang for a long time. Upgrade to version 5.0.145.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-23w4-rpc6-wpcc>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
