          "22 September 2026. WordPress 7.1.2 fixed a critical flaw, CVE-2026-87902 (GHSA-7hp8-65ch-5whp), in which an unauthenticated attacker could, where server and theme conditions were met, make template resolution include a local PHP file and reach remote code execution. 7.1.1 on 17 September and 7.1.3 on 6 October fixed 18 further security issues. All were published by the project with the fix and backported, and we found no report of exploitation in the release posts, so we deduct 5 of a possible 15. https://wordpress.org/news/2026/09/wordpress-7-1-2-release/ ; https://wordpress.org/news/2026/10/wordpress-7-1-3-maintenance-and-security-release/"

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**WordPress.** The REST API is part of core, and a post created without a status is saved as a draft with revisions kept on the owner's server. Application Passwords carry no scopes, so limits come only from the user's role. Revisions can be read and deleted but not restored over REST, and a critical flaw was fixed on 22 September 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### WordPress\n\n1. Ask the owner for a dedicated user with the lowest role that fits. A Contributor can draft and edit its own posts but can't publish them\n2. Send the Application Password as Basic auth over HTTPS only. Core disables Application Passwords on plain HTTP outside a local environment\n3. Upload a file with POST `/wp-json/wp/v2/media` first, then set `featured_media` or reference the returned URL in the post content\n4. To roll back, GET `/wp/v2/posts/\u003cid\u003e/revisions/\u003crev\u003e?context=edit` and POST its title and content to the post. There's no restore route\n5. Pass `_fields=id,status,link,modified` on lists and read X-WP-TotalPages. `per_page` stops at 100\n\n## Questions\n\n### Which is better for AI agents, ButterCMS or WordPress?\n\nWordPress scores 64.8 (B) on agent readiness against ButterCMS's 53.3 (D), and leads in 5 of 7 scored categories. ButterCMS leads on reliability and schema \u0026 documentation.\n\n### Do ButterCMS and WordPress need an API key?\n\nBoth need an API key.\n\n### Can an agent call ButterCMS and WordPress without installing anything?\n\nButterCMS has a hosted endpoint at https://api.buttercms.com/v2. WordPress runs on your own machine, with no hosted endpoint listed.\n\n### Are ButterCMS and WordPress open source?\n\nNo open-source release is listed for ButterCMS. WordPress is open source (GPL-2.0-or-later. The MCP Adapter plugin is GPL-2.0-or-later too).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/buttercms-vs-wordpress.json, and with the fewest tokens: https://www.anchorterminal.com/compare/buttercms-vs-wordpress.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"buttercms\", \"b\": \"wordpress\"}`.
