Published by the GitHub Advisory Database at 19 Oct 2018, 16:40 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.apache.cxf:cxf-rt-transports-http` (Maven): affected `>=3.2.0, <3.2.5 || <3.1.16`; fixed in `3.2.5`, `3.1.16`
- `org.apache.cxf:apache-cxf` (Maven): affected `>=3.2.0, <3.2.5 || <3.1.16`; fixed in `3.2.5`, `3.1.16`

## Machine-written summary

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

> Apache CXF (org.apache.cxf:cxf-rt-transports-http and org.apache.cxf:apache-cxf) versions 3.2.0 before 3.2.5 and before 3.1.16 do not properly report TLS hostname verification failures when the com.sun.net.ssl implementation is enabled through the java.protocol.handler.pkgs system property. An attacker in a man-in-the-middle position can then intercept connections from a CXF client without the error being raised. Upgrade to version 3.2.5 or 3.1.16.

## 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-jc7r-v6fg-2gpf>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
