🚀 Thanks for opening this pull request! We appreciate your effort in improving the project. Please let us know once your pull request is ready for review.

Tip

• Keep pull requests small. Large PRs will be rejected. Break complex features into smaller, incremental PRs.
• Use Test Driven Development. Write failing tests before implementing functionality. Ensure tests pass.
• Group code into logical blocks. Add a short comment before each block to explain its purpose.
• We offer conceptual guidance. Coding is up to you. PRs must be merge-ready for human review.
• Our review focuses on concept, not quality. PRs with code issues will be rejected. Use an AI agent.
• Human review time is precious. Avoid review ping-pong. Inspect and test your AI-generated code.

Note

Please respond to review comments from AI agents just like you would to comments from a human reviewer. Let the reviewer resolve their own comments, unless they have reviewed and accepted your commit, or agreed with your explanation for why the feedback was incorrect.

Caution

Pull requests must be written using an AI agent with human supervision. Pull requests written entirely by a human will likely be rejected, because of lower code quality, higher review effort and the higher risk of introducing bugs. Please note that AI review comments on this pull request alone do not satisfy this requirement. Our CI and AI review are safeguards, not development tools. If many issues are flagged, rethink your development approach. Invest more effort in planning and design rather than using review cycles to fix low-quality code.

Walkthrough

The controller now rejects malformed $relatedTo constraints before authorization. New vulnerability tests cover operator-valued and non-string fields, result and count behavior, and a valid relation query.

Changes

$relatedTo constraint validation

Layer / File(s)	Summary
Validate constraints and verify query behavior src/Controllers/DatabaseController.js, spec/vulnerabilities.spec.js	reduceRelationKeys checks that the owner object exists and that its className and objectId, and the relation key, are strings. Tests cover invalid constraints, result and count behavior, master-key requests, and a valid pointer.
