Parse Server: LiveQuery discloses object data to a subscriber across an ACL read-access change
CVE-2026-57481
Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1-alpha.13 and 8.6.83, a LiveQuery subscriber could receive object field values they were not authorized to read when a single save changed both an object field and the subscriber's ACL read access, because leave and enter events included the wrong object state. This issue is fixed in versions 9.9.1-alpha.13 and 8.6.83.
