Published by the GitHub Advisory Database at 4 Sept 2026, 20:50 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `surrealdb-core` (crates.io): affected `<3.2.0`; fixed in `3.2.0`

## Machine-written summary

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

> SurrealDB (surrealdb-core versions before 3.2.0) lets write statements inside a PERMISSIONS ... WHERE clause run with permission enforcement disabled, so evaluating a permission check can write to tables the caller cannot otherwise write. An attacker needs permission to perform an operation guarded by such a clause, which must already be defined in the database; databases with FULL, NONE, or read-only clauses are not affected. Upgrade to surrealdb-core 3.2.0 or later. Users who cannot upgrade can remove write statements from their PERMISSIONS clauses and limit who can define schema.

Written 8 Nov 2026.

## 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-66r2-5gwj-gxm2>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
