Review Change Stack

Walkthrough

The comments service now checks post access before reading comments, replies, editing, deleting, liking, or disliking. The controller derives a single post scope from legacy filters and reports malformed filters as bad requests. Tests cover member visibility, restricted posts, admin access, filter validation, reply pagination, vote mutations, and comment changes.

Suggested reviewers: 9larsons, jonatansberg, kevinansfield

Merge Risk: 🟡 Moderate · up to 36025

The PR adds a new end-to-end test as JavaScript even though new test files must use TypeScript; it should be renamed and annotated before merge to meet repository requirements.

Full details: Type-Safe Boundaries

Explanation

The PR adds a new HTTP-input path that uses options.post_id in #checkPostAccessForRead and passes it directly to models.Post.findOne({id: postId}). The member comments endpoint allows post_id but declares no type validation. The repository also documents that repeated query parameters can arrive as arrays, while this code checks only truthiness. Therefore a non-string HTTP value can reach the database lookup without boundary validation. The new filter path does parse NQL and checks that an inferred post_id is a string, but it does not validate a directly supplied post_id. No new any, unchecked as, @ts-nocheck, or @ts-ignore was found.

Resolution

Validate the directly supplied post_id at the HTTP boundary before calling the comments controller or service. Use a Zod schema that accepts an optional non-empty string and rejects arrays and other values, then pass the parsed value onward. Keep the existing NQL parse for filter input and validate its inferred post ID with the same schema. Add coverage for repeated or otherwise non-string post_id query parameters.

Full details: New Files Are Typescript

Explanation

The PR adds ghost/core/test/e2e-api/members-comments/post-access.test.js as a new 234-line JavaScript test source file. The file is outside the listed exceptions: migrations, apps/ember-admin/, scripts/, and docker/. The other JavaScript files are pre-existing modifications and do not fail this check.
