CVE-2026-113666 Details
Description
ApostropheCMS is an open-source Node.js content management system. Prior to 1.1.0 of db-connect and 4.33.0 of ApostropheCMS, an account with view-draft access can submit a projection exclusion path that traverses through a constructor prototype chain to a shared prototype member when a consumer uses a SQLite, PostgreSQL, or multipostgres adapter and has a matching document. Every editing role has view-draft access, while guestApiAccess broadens this prerequisite to any logged-in account. The unsetNestedField helper then deletes the shared runtime member, causing persistent process-wide integrity and availability effects; the default MongoDB adapter is not affected. This issue is fixed in db-connect 1.1.0 and ApostropheCMS 4.33.0.
A vulnerability in ApostropheCMS and its db-connect package prior to version 1.1.0 has been identified. The issue allows an authenticated user with view-draft access to manipulate the projection exclusion path, traversing the constructor prototype chain to delete shared prototype members. This vulnerability is present when using SQLite, PostgreSQL, or multipostgres adapters, and can cause persistent process-wide integrity and availability issues. The default MongoDB adapter is not affected.
Users can update to ApostropheCMS version 4.33.0 and db-connect version 1.1.0, where this vulnerability has been fixed.
