## Machine-written summary

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

> WSO2 API Manager versions before 2.1.0 are vulnerable to XML External Entity (XXE) injection in the gateway component, caused by insufficient validation of XML input in crafted URL paths. An unauthenticated remote attacker can read files from the server's filesystem or cause a denial of service, with the extent of file exposure depending on the JDK version. Upgrade to version 2.1.0 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-h94w-8qhg-3xmc>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
