CVE-2026-33539 MongoDB — Exploit & Vulnerability Details HIGH

Parameter	Value
CVSS	8.6 (HIGH)
Affected Versions	9.0.0 — 9.6.0
Fixed In	8.6.59
Type	CWE-89 (SQL Injection)
Vendor	MongoDB
Public PoC	No

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.59 and 9.6.0-alpha.53, an attacker with master key access can execute arbitrary SQL statements on the PostgreSQL database by injecting SQL metacharacters into field name parameters of the aggregate $group pipeline stage or the distinct operation. This allows privilege escalation from Parse Server application-level administrator to PostgreSQL database-level access.

Only Parse Server deployments using PostgreSQL are affected. MongoDB deployments are not affected. This issue has been patched in versions 8.6.59 and 9.6.0-alpha.53.
