Pull Request

Issue

Role hierarchy cycle detection does not record a role with object ID __proto__ as visited

Tasks

  • Add tests

Summary by CodeRabbit

  • Bug Fixes
    • Fixed role resolution for roles with special identifiers or self-referential relationships. Role lookups now avoid repeating queries for roles already encountered, allowing membership checks involving these role relationships to complete reliably without getting stuck in repeated lookups.

🚀 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

Role resolution now tracks queried role IDs with a Set. Unit and integration tests cover resolution of a self-referential role with ID __proto__.

Changes: Cyclic role resolution

Layer / File(s) Summary
Role traversal and cycle coverage
src/Auth.js, spec/ParseRole.spec.js
_getAllRolesNamesForRoleIds uses a Set to track queried role IDs. Unit and integration tests check resolution of a self-referential __proto__ role.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 669c9

The role traversal change has direct unit coverage, but its REST integration test may pass without proving that CyclicRole grants access. This is a bounded test gap; the implementation change itself is supported by the inspected code.

Full details: Security Check

Explanation

The pull request changes role-cycle tracking from a plain object to a Set, and the diff records each role ID before querying parents. This removes the __proto__ key collision and prevents repeated role queries in self-cycles. The added tests cover both the direct resolver and a REST-backed cyclic role. No new security-vulnerability pattern is introduced by the changed code.

Full details: Engage In Review Feedback

Explanation

The prior review feedback remains unresolved. The current test queries an unrestricted TestObject, asserts only that the query resolves, and allows lookups to be zero with toBeLessThanOrEqual(1) (spec/ParseRole.spec.js:252-256). The second commit only adds a getRolesForUser spy and does not implement the requested role-restricted authorization assertion. The supplied review thread is still unresolved, and no reviewer retraction or convincing author response is present.

Resolution

Engage in the unresolved review thread. Then either update spec/ParseRole.spec.js to query an object readable only by CyclicRole, assert that the user can read it, and require exactly one role lookup, or convince the reviewer of an alternative and obtain feedback retraction.
