How to Fix CVE-2025-23204

To remediate this vulnerability, upgrade all affected Api platform/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

api-platform/core fixed: 3.3.15 
Upgrade api-platform/core to 3.3.15
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for api-platform/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-23204, inspect your project dependencies for Api platform/core:

inspect dependencies for api-platform/core

Analyze the terminal output to locate any version of Api platform/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.15), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Api platform/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
