## Affected packages

- `api-platform/core` (Packagist): affected `>=3.3.8, <3.3.15`; fixed in `3.3.15`

## Machine-written summary

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

> API Platform Core versions 3.3.8 before 3.3.15 have a GraphQL access-check bug: a security check meant to run after resolvers is replaced by another check because a switch clause lacks a break. Per the source, the impact applies only when a GraphQL operation has a security after resolver and no security check inside security, and the source gives few further details on exploitation. Upgrade api-platform/core to version 3.3.15, which is the listed fixed version.

## 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-7mxx-3cgm-xxv3>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
