Description

Parse Server before 8.6.114 and 9.0.0 before 9.10.6-alpha.6 returns field values in object create responses to callers that lack read access to the created object through class-level permissions or the object's ACL. An attacker with create permission can create objects to obtain values set by Cloud Code triggers, schema defaults, and the class default ACL.

Executive Summary

This vulnerability affects Parse Server versions before 8.6.114 and 9.0.0 before 9.10.6-alpha.6. It allows an attacker with create permission to obtain sensitive field values in object create responses even if they lack read access to the created object. The server returns these values despite class-level permissions or the object's ACL restricting access.

Impact Analysis

An attacker could exploit this to access sensitive data set by Cloud Code triggers, schema defaults, or class default ACLs. This may lead to unauthorized disclosure of confidential information, though the impact is rated as low severity with no integrity or availability impact.

Mitigation Strategies

Upgrade parse-server to version 8.6.114 or later, or 9.10.6-alpha.6 or later. Avoid granting create permissions to clients that should not receive sensitive field values.
