## Machine-written summary

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

> Liferay Portal 7.2.0 through 7.4.3.18 and Liferay DXP 7.2 before fix pack 19, 7.3 before update 4, and 7.4 before update 19 are affected. A remote attacker can bypass the HtmlUtil.escapeRedirect filter using the Unicode replacement character, redirecting users to arbitrary external URLs through parameters such as redirect. Upgrade Liferay Portal to 7.4.3.19-ga19 or Liferay DXP to 7.2.10.fp19, 7.3.10.u4, or 7.4.13.u19.

## 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-548x-j6x6-hcv4>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
