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

> CrateDB (io.crate:crate) before 6.2.8, and 6.3.0 before 6.3.2, skips privilege checks on its blob HTTP API. Any authenticated user can read or delete a blob whose SHA-1 digest they know, and can upload blobs to any blob table, regardless of grants. Upgrade to 6.2.8 or 6.3.2.

## 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-2xv8-gjwh-fv8p>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
