🚀 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

RestWrite now skips selected dot-notation writes that target pointer identifiers. Trigger logging uses safe serialization. New tests cover pointer updates, trigger-visible state, batch and non-master updates, and serialization errors.

Changes: Pointer dot-notation updates

Layer / File(s)	Summary
Filter pointer ID dot-notation paths src/RestWrite.js	RestWrite builds a lookup root from original data and whole-field writes. It skips null or operation-valued dot-notation writes that target a pointer’s id or objectId.
Safeguard trigger logging and verify behavior src/Utils.js, src/triggers.js, spec/Utils.spec.js, spec/vulnerabilities.spec.js	Trigger logging uses Utils.safeToJSON, which returns undefined if toJSON() throws. Tests cover successful and failed serialization, pointer updates, trigger-visible state, batch updates, and non-master updates.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Suggested reviewers: dblythy

Merge Risk: ⚪ Minimal · up to a6ba8

The investigated pointer update preserves the stored pointer and no actionable merge-blocking risk remains after normal checks.

✅ Pre-merge checks override applied

The pre-merge checks have been overridden successfully. You can now proceed with the merge.

Full details: Security Check

Explanation

No new security vulnerability is evident in the reviewed diff. RestWrite now skips null or operation dot-notation writes that target a pointer id or objectId, which prevents malformed trigger objects. Utils.safeToJSON prevents serialization failures from interrupting trigger logging. The added vulnerability tests cover master, non-master, batch, nested-pointer, and revert paths. No unsafe evaluation, credential exposure, or permission bypass was introduced.

🟡 Minor · Skip non-null writes to pointer identifiers in the dot-notation branch. · RestWrite.js:2080-2087

src/RestWrite.js:2080-2087
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Skip non-null writes to pointer identifiers in the dot-notation branch.

A non-null owner.id value bypasses the new guard and enters the subdocument branch. That branch assigns the value to the Parse.Object pointer returned by updatedObject.get('owner'). Parse uses that id when it serializes the pointer, so a trigger can receive a pointer for a different object than the stored pointer.

Suggested fix

-      } else {
+      } else if (!targetsPointerId(pointerRoot, key)) {
         // subdocument key with dot notation { 'x.y': v } => { 'x': { 'y' : v } })
         const splittedKey = key.split('.');

skip the subdocument assignment when `targetsPointerId(pointerRoot, key)` is
