📝 Walkthrough

The refresh flow now saves threaded-reply metadata with form state. After comments are replaced, it restores the reply target and respond-container position, or resets the form when the target is missing.

Changes: Threaded reply state

Layer / File(s) Summary
Reply metadata and field restoration
src/js/frontend/wp-ajaxify-comments.js
New helpers capture and restore reply metadata. Saved nonzero comment_parent values can replace a zero value in the refreshed form; other populated fields remain unchanged.
Capture state before refresh
src/js/frontend/wp-ajaxify-comments.js
The multiple-container path saves reply state per post. The single-container path saves reply metadata with serialized form fields.
Restore state after replacement
src/js/frontend/wp-ajaxify-comments.js
Both replacement paths restore threaded-reply state after restoring form fields.

Priority: ⚪ Not assessed

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

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: ronaldhuereca

Merge Risk: 🟡 Moderate · up to 8dd3b

After an automatic comments refresh, a restored threaded reply can carry the parent comment's ID as the post ID. The reply could then be rejected or attached to the wrong post. Pass the form's actual post ID before merging.

Security architecture risk: 🟡 Moderate · up to 8dd3b

Reply restoration may change which post receives a comment because the native handler is given the saved comment ID where a post ID is expected. Per-post capture and missing-target recovery provide useful containment, but the deployed handler and server-side validation were unavailable to confirm the outcome.

Retained concerns

  • Medium · security · inferred: The new native restoration call passes the saved comment-parent ID as moveForm’s fourth argument without preserving the owning post ID. Under WordPress’s expected post-ID parameter contract, this can retarget comment_post_ID; the subsequent assignment repairs only comment_parent. A later submission could therefore reach a different post or fail. Cross-post disclosure is not verified because the deployed native handler and server validation were unavailable.
Security review details

Security Blast Radius

  • inferred — The directly affected state is the active browser page’s comment forms. The native-handler concern could extend a submission to another post whose ID matches the saved comment ID, subject to server acceptance. No tenant, service or privilege escalation was established.

Security Findings and Attack Paths

  • inferred — The plausible failure path is an active reply followed by refresh, native restoration using the comment ID as the expected post-ID argument, and a later submission with altered post ownership. No attacker-controlled route to unauthorized publication or disclosure was verified; the native and server implementations remain decisive missing evidence.

Trust Boundaries and Controls

  • observed — LoadComments still invokes the existing cross-domain check before capture and request dispatch. Multi-form capture is post-keyed, and the direct DOM fallback does not explicitly alter comment_post_ID. These controls narrow the concern to restoration and native-handler ownership rather than a newly exposed loading API.

Explanation

Issue #80 requires reply-state restoration in the source and generated assets. The available source summary reports capture and restoration of the reply target, form position, cancel state, post scoping, absent-target fallback, and zero-only parent restoration. The PR reports lint, build, and syntax checks. However, all four generated dist files are excluded from review, so their behavior and source alignment cannot be verified. The issue's browser acceptance checks are manual and do not create an unmet automated-test requirement.

official WordPress core comment-reply.js addComment.moveForm signature comment_post_ID

💡 Result:

In WordPress core, the signature is:

```js
addComment.moveForm(commId, parentId, respondId, postId)
```

`postId` is optional: when provided, `moveForm` assigns it to the form element with ID `comment_post_ID`. It also sets `comment_parent` to `parentId`. ([core.trac.wordpress.org](https://core.trac.wordpress.org/changeset/35593))

So `postId` is the **fourth argument**—it’s not the `comment_post_ID` element itself. The cited source is a 2015 core changeset; it establishes that historical implementation, not the exact contents of every current WordPress version.([core.trac.wordpress.org](https://core.trac.wordpress.org/changeset/35593))

Citations:

- 1: https://core.trac.wordpress.org/changeset/35593
- 2: https://core.trac.wordpress.org/changeset/35593

Pass the form’s post ID to addComment.moveForm.

WordPress defines moveForm as moveForm(commId, parentId, respondId, postId). The current fourth argument is the parent comment ID, so native reply handling can write that value to comment_post_ID. The second argument must remain the comment_parent field ID.
