CVE-2026-31871: Parse Server vulnerable to SQL Injection via dot-notation sub-key name in `Increment` operation on PostgreSQL

criticalCVSS 4.0 9.3GHSA-gqpp-xgvh-9h7h

Impact 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.

Advisory details

From the GitHub Advisory Database (CC BY 4.0).

Impact

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.

Patches

The fix escapes single quotes in the sub-key name before interpolating it into the SQL query, preventing breakout from SQL string literals.

Workarounds

There is no known workaround.
