## Affected packages

- `surrealdb` (crates.io): affected `<3.1.0`; fixed in `3.1.0`

## Machine-written summary

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

> SurrealDB versions before 3.1.0 (crates.io package surrealdb) fail to apply port-specific --deny-net rules to HTTP redirect targets. An authenticated user permitted to call http::\* functions can point a redirect from an allowed host at a denied host and port, and the request is followed anyway. Upgrade to surrealdb 3.1.0 or later. If upgrading is not possible, replace port-specific deny rules with host-only deny rules or disable http::\* for untrusted users.

## 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-97vg-427p-8hx5>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
