          "3 September to 1 October 2026. Ghost published 20 security advisories in five weeks, one critical, ten high, eight moderate and one low. They include GHSA-q734-xjgc-vpj9 (critical, suspended staff could reactivate accounts through password reset), GHSA-788w-68h3-cvxp (high, CVSS 8.8, remote code execution through bookmark card images in 6.56.0 to 6.65.0, fixed in 6.67.0) and GHSA-jj74-hc2q-xrvm (high, remote code execution through theme translation files). Several could be triggered by any staff user, Contributors included. All were published by the vendor with a fixed version, and we found no report of exploitation in the advisories we read, so we deduct 7 of a possible 15. https://github.com/TryGhost/Ghost/security/advisories ; https://github.com/TryGhost/Ghost/security/advisories/GHSA-788w-68h3-cvxp"

The Write API is a paid add-on from the $249 plan, capped at 2,000 or 5,000 calls a month. Writes answer 202 with no identifier, support rotates tokens, and the terms are an undated website document.\n\n**Ghost.** A create needs only a title, updates are checked against `updated_at` so a stale write is refused, and a Contributor's staff token can draft without being able to publish. The Admin API has no OpenAPI file and one fixed permission set per integration, and 20 security advisories were published between 3 September and 1 October 2026.\n\n## Before you call either\n\n### ButterCMS\n\n1. End every path with a slash. A missing slash returns a 301, and the vendor counts the redirect and the retry as two API calls\n2. Send the write token only as `Authorization: Token \u003ctoken\u003e`. The `auth_token` query parameter works for reads only\n3. On page creation send every field key of the page type, with empty strings for fields left blank\n4. A 202 means queued, not saved. Read the entry back with `preview=1` to confirm, and check a slug exists before retrying a create\n5. Call the REST API directly for writes. The JavaScript SDK 3.0.3 has list, retrieve and search methods only\n\n### Ghost\n\n1. Sign a fresh HS256 token for each batch of calls. Decode the hex secret to bytes, set `kid` to the key id, `aud` to `/admin/` and `exp` at most 5 minutes ahead\n2. Set `status` to `draft` on every create unless told to publish, and publish later with a PUT that sets `status` to `published`\n3. GET the post before each PUT and send its `updated_at` back. Tags and authors in a PUT replace the existing lists\n4. Send content as a Lexical JSON string, or add `?source=html` and send `html`. The HTML conversion is lossy unless wrapped in an HTML card\n5. Page through lists with `limit` up to 100 and `page`. Since Ghost 6.0 `limit=all` returns 100 items without an error\n\n## Questions\n\n### Which is better for AI agents, ButterCMS or Ghost?\n\nGhost scores 58.3 (C) on agent readiness against ButterCMS's 53.3 (D), and leads in 5 of 7 scored categories. ButterCMS leads on schema \u0026 documentation.\n\n### Do ButterCMS and Ghost need an API key?\n\nBoth need an API key.\n\n### Can an agent call ButterCMS and Ghost without installing anything?\n\nButterCMS has a hosted endpoint at https://api.buttercms.com/v2. No hosted endpoint is listed for Ghost.\n\n### Are ButterCMS and Ghost open source?\n\nNo open-source release is listed for ButterCMS. Ghost is open source (MIT, copyright Ghost Foundation. Ghost(Pro) is a paid hosting service under the Ghost Foundation's terms).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/buttercms-vs-ghost.json, and with the fewest tokens: https://www.anchorterminal.com/compare/buttercms-vs-ghost.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"buttercms\", \"b\": \"ghost\"}`.
