2DescriptionGitHub 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.5 and 8.6.31, a SQL injection vulnerability exists in the PostgreSQL storage adapter when processing Increment operations on nested object fields using dot notation (e.g., stats.counter). The sub-key name is interpolated directly into SQL string literals without escaping. An attacker who can send write requests to the Parse Server REST API can inject arbitrary SQL via a crafted sub-key name containing single quotes, potentially executing commands or reading data from the database, bypassing CLPs and ACLs. Only Postgres deployments are affected. This vulnerability is fixed in 9.6.0-alpha.5 and 8.6.31.
Executive ViewAI
Parse Server deployments running versions up to 9.6.0 are vulnerable to SQL injection attacks that could allow attackers to access, modify, or delete sensitive database contents without authentication. Organizations using Parse Server as their backend infrastructure face immediate risk of data breach and operational disruption until this critical vulnerability is remediated.
Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts; enforce strict input validation and parameterized queries in application code; restrict database network access through segmentation and firewall rules; disable unnecessary database features and stored procedures; enable detailed audit logging for all database queries; consider temporary service degradation by disabling affected Parse Server features until patching is available; monitor for unusual database query patterns and access anomalies.
