ApostropheCMS: Authenticated projection-exclusion prototype-member deletion in @apostrophecms/db-connect causes process-wide denial of service

Type: advisorySource: Official CVE List1 source record

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.
