Exploitation Conditions

Parse Server instances with protectedFields configured on classes and LiveQuery subscriptions enabled. No authentication required against default deployments exposing LiveQuery endpoints.

Impact

Exposed information (credentials, internal paths, user data, configuration) can be leveraged for further attacks or regulatory violations.

Exploit ScenarioDerived

An attacker triggers error conditions or accesses improperly protected endpoints to extract sensitive internal information from the application.

AnalysisAIv1 – Mar 12, 2026

Impact

An attacker can exploit LiveQuery subscriptions to infer the values of protected fields without directly receiving them. By subscribing with a WHERE clause that references a protected field (including via dot-notation or $regex), the attacker can observe whether LiveQuery events are delivered for matching objects. This creates a boolean oracle that leaks protected field values. The attack affects any class that has both protectedFields configured in Class-Level Permissions and LiveQuery enabled.

Patches

The fix adds validation of the LiveQuery subscription WHERE clause against the class's protected fields, mirroring the existing REST API validation. If a subscription's WHERE clause references a protected field directly, via dot-notation, or inside $or / $and / $nor operators, the subscription is rejected with a permission error. This is applied during subscription creation, so existing event delivery paths are not affected.

Workarounds

Disable LiveQuery for classes that use protectedFields in their Class-Level Permissions, or remove protectedFields from classes that require LiveQuery.

DescriptionGitHub Advisory

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.9 and 8.6.35, an attacker can exploit LiveQuery subscriptions to infer the values of protected fields without directly receiving them. By subscribing with a WHERE clause that references a protected field (including via dot-notation or $regex), the attacker can observe whether LiveQuery events are delivered for matching objects. This creates a boolean oracle that leaks protected field values. The attack affects any class that has both protectedFields configured in Class-Level Permissions and LiveQuery enabled. This vulnerability is fixed in 9.6.0-alpha.9 and 8.6.35.

Executive ViewAI

Why It Matters

A vulnerability in Parse Server's LiveQuery feature allows attackers to bypass access controls and discover sensitive protected field values through subscription manipulation. Organizations using Parse Server with both protected fields and LiveQuery enabled risk unauthorized data exposure and potential compliance violations.

Business Impact: High
Compensating Controls

Disable LiveQuery feature entirely if not critical to operations; restrict LiveQuery endpoint access via network firewall/WAF to trusted applications only; implement API rate limiting and anomaly detection on subscription requests; conduct audit logs review for suspicious LiveQuery subscription patterns; apply principle of least privilege to service accounts accessing LiveQuery; consider temporary application of query filtering at the API gateway layer to block WHERE clauses targeting protected fields.
