CVE-2026-112952 Details
Description
ApostropheCMS is an open-source Node.js content management system. Prior to 4.34.0, 'POST /api/v1/@apostrophecms/doc/slugTaken' with body { "slug": "target-slug" } returns a boolean indicating whether a slug is in use across all document types and visibility levels, with no permission or type filter. Any logged-in user (including editors) can enumerate the slug space of private pages, drafts, and archived content. This issue is fixed in version 4.34.0.
A vulnerability in ApostropheCMS prior to version 4.34.0 allows any logged-in user, including editors, to misuse the 'slugTaken' API endpoint. This endpoint checks if a specific slug is in use across all document types and visibility levels, without any permission or type filters. As a result, authenticated users can enumerate slugs of private pages, drafts, and archived content, effectively mapping the entire content inventory of the CMS, including items they are not permitted to view.
Users can update to ApostropheCMS version 4.34.0 or later, where this vulnerability has been fixed.
