API Platform Core does not call GraphQl securityAfterResolver

  • Disclosed: 24.03.2025
  • Updated: 11.10.2026 10:22

Summary

A security check that gets called after GraphQl resolvers is always replaced by another one as there's no break in this clause: https://github.com/api-platform/core/pull/6444/files#diff-09e3c2cfe12a2ce65bd6c983c7ca6bfcf783f852b8d0554bb938e8ebf5e5fa65R56

https://github.com/soyuka/core/blob/7e2e8f9ff322ac5f6eb5f65baf432bffdca0fd51/src/Symfony/Security/State/AccessCheckerProvider.php#L49-L57

PoC

Create a graphql endpoint with a security after resolver.

Impact

As this fallsback to security, the impact is there only when there's only a security after resolver and none inside security. The test at https://github.com/api-platform/core/pull/6444 is probably broken.
