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

> Apache Gravitino versions 1.0.0 through 1.2.1 (the apache-gravitino package) are affected by a server-side request forgery flaw in the JobManager. An authenticated user can supply job template URIs that are not validated, causing the server to send HTTP requests to internal network hosts and cloud metadata endpoints. Upgrade to apache-gravitino 1.3.0, which fixes the issue.

## 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/PYSEC-2026-3442>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
