## Affected packages

- `com.liferay:com.liferay.remote.app.web` (Maven): affected `<2.0.21`; fixed in `2.0.21`
- `com.liferay.portal:release.dxp.bom` (Maven): affected `<7.4.13.u5`; fixed in `7.4.13.u5`

## Machine-written summary

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

> Liferay's Remote App module (com.liferay.remote.app.web) before 2.0.21 and the Liferay DXP release BOM (release.dxp.bom) before 7.4.13.u5 do not verify the origin of incoming event messages. An attacker who can get a user to interact with a crafted page could exfiltrate the CSRF token. Upgrade com.liferay.remote.app.web to 2.0.21 or release.dxp.bom to 7.4.13.u5.

## 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-ghw5-998m-vw4w>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
