Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.6 and 8.6.32, the protectedFields class-level permission (CLP) can be bypassed using dot-notation in query WHERE clauses and sort parameters. An attacker can use dot-notation to query or sort by sub-fields of a protected field, enabling a binary oracle attack to enumerate protected field values. This affects both MongoDB and PostgreSQL deployments. This vulnerability is fixed in 9.6.0-alpha.6 and 8.6.32.
