Fixed free members subscribing to paid-only newsletters by acburdine · Pull Request #30693 · TryGhost/Ghost

acburdine · 2026-09-10T18:38:09Z

Newsletters with visibility: paid are meant for paying members. The default signup path already respects that (getSubscribeOnSignupNewsletters filters to visibility:members), but explicitly requested newsletters didn't:

Signup (POST /members/api/send-magic-link): _validateNewsletters checked existence and archived status, not visibility.
Unsubscribe link (PUT /members/api/member/newsletters) and account (PUT /members/api/member/): newsletter IDs went straight to the member repository.

The email segmenter already excludes free members from paid newsletters (status:-free), so nothing was delivered. But the subscriptions were recorded, and subscriber counts were wrong.

Changes

_validateNewsletters now selects visibility and drops non-members newsletters unless allowPaid is set. Subscription checkouts and gift signups pass it. Plain signups don't. Paid-only newsletters are dropped rather than rejected: Portal lists every active newsletter regardless of visibility, so a pre-ticked paid one would otherwise fail the whole signup.
MemberAccountService.edit drops newly added paid-only newsletters for free members and keeps any they already have (for example, ones added by staff). updateMemberNewsletters now goes through account.edit as well, so both self-service paths share the rule.

Testing

Unit: _validateNewsletters, sendMagicLink (free vs gift signup), subscription checkout, the new account-service.test.ts, and middleware routing.
E2E: a free member can't add a paid-only newsletter through the unsubscribe-link endpoint. This runs the real visibility:-members query. The send-magic-link and members middleware e2e suites pass.

Out of scope

visibility: paid still has no Admin UI and no isIn validation, and Portal doesn't hide paid-only newsletters from free members. Those belong to finishing the paid-newsletters feature.

🤖 Generated with Claude Code

no ref Newsletters with `visibility: paid` are meant for paying members, and the default signup path already only auto-subscribes new members to members-visibility newsletters. Explicitly named newsletters skipped that check: a free signup via send-magic-link, or a free member updating their subscriptions from the unsubscribe link or their account, could add a paid-only newsletter. Nothing was delivered, since the email segmenter excludes free members from paid newsletters, but the subscription and subscriber counts were wrong. Free signups now drop paid-only newsletters rather than rejecting them, because Portal lists every active newsletter regardless of visibility and a pre-ticked paid one would otherwise fail the whole signup. Subscription checkouts and gift signups keep them, since those members won't be free. Member self-service updates now go through the account service from both the unsubscribe link and the account endpoint, so the rule lives in one place. It keeps a free member's existing paid-only subscriptions (e.g. ones added by staff) but won't add new ones. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Walkthrough

MemberAccountService now prevents free members from adding new paid-only newsletters while preserving newsletters they already have. Signup and checkout validation now filters paid-only newsletters unless the flow permits them. Member newsletter middleware uses the account edit API. Unit and end-to-end tests cover member edits, signup flows, and middleware behavior.

Merge Risk: 🟡 Moderate · up to 19bf3

The change blocks free members from adding paid-only newsletters, but malformed newsletter entries can still reach member updates and cause update failures or relation-handling problems. Validate each newsletter item before merging.

Full details: Type-Safe Boundaries

Explanation

The PR introduces a new unvalidated HTTP-data path in the changed TypeScript service. updateMemberNewsletters forwards _.pick(req.body, ...) directly to membersService.api.account.edit (the changed routing in middleware.js:381-388), and the account endpoint also passes frame.data directly to account.edit (members-account.ts:55-60). The new account-service.ts logic then treats changes.newsletters as Array<{id?: string}> after only an Array.isArray check and reads newsletter.id before writing it. No Zod parse or equivalent schema validation exists in this path. The new interface is only a compile-time assertion and does not validate request data at runtime. The added code has no any, unchecked as, @ts-ignore, or @ts-nocheck, and no duplicate Zod shape was found; the failure is the new boundary-data consumption without validation.

Resolution

Add a Zod schema for the member update payload at the HTTP boundary. Parse frame.data and the unsubscribe-link request body before calling account.edit, including an array schema whose newsletter entries require the expected string id shape and schemas for the other writable fields. Use z.infer for the service input type instead of asserting Array<{id?: string}>. Reject invalid payloads before #withoutNewPaidNewsletters and the repository update.
