## Affected packages

- `io.quarkiverse.openapi.generator:quarkus-openapi-generator` (Maven): affected `<2.16.0`; fixed in `2.16.0`

## Machine-written summary

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

> Quarkus-openapi-generator versions before 2.16.0 are affected by a Zip Slip path traversal in the unzip() method of ApicurioCodegenWrapper, which writes ZIP entries without checking that they stay inside the output directory. An attacker who can serve a crafted ZIP archive to the code generation step, such as through a controlled or intercepted Apicurio registry connection, could write arbitrary files on the build machine. Upgrade to version 2.16.0 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-jx2w-vp7f-456q>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
