## Machine-written summary

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

> Quarkus HTTP core (io.quarkus.http:quarkus-http-core) versions before 5.3.4 incorrectly parse cookies that contain certain value-delimiting characters. An attacker who can send requests to the application can craft a cookie value to read HttpOnly cookie values or add spoofed cookies, affecting data confidentiality and integrity. Upgrade to version 5.3.4 or later.

## 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-cxrx-q234-m22m>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
