Published by the GitHub Advisory Database at 17 Jul 2024, 15:52 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `dbt-core` (PyPI): affected `>=1.6.0, <1.6.14 || >=1.7.0, <1.7.14`; fixed in `1.6.14`, `1.7.14`

## Machine-written summary

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

> dbt-core versions 1.6.0 before 1.6.14 and 1.7.0 before 1.7.14 are affected. A materialization defined in an installed package that shares a name with a built-in materialization was preferred by default, so a malicious package could replace dbt's behavior with harmful code. Upgrade to dbt-core 1.6.14, 1.7.14, or 1.8.0 or later. For older versions, set the flag require_explicit_package_overrides_for_builtin_materializations to False in dbt_project.yml to require explicit overrides.

## 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-p3f3-5ccg-83xq>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
