GHSA-P2W6-RMH7-W8Q3

Vulnerability from github – Published: 2026-03-24 19:12 – Updated: 2026-03-27 21:54

Summary

Parse Server has SQL Injection through aggregate and distinct field names in PostgreSQL adapter

Details

Impact

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.

Patches

Field names in the aggregate $group._id object values and distinct dot-notation parameters are now validated to only contain alphanumeric characters and underscores, preventing SQL injection via the :raw interpolation used in the PostgreSQL storage adapter.

Workarounds

No workaround. Upgrade to a patched version.

Severity

8.6 (High)

CVE-2026-33539 (GCVE-0-2026-33539)

Vulnerability from cvelistv5 – Published: 2026-03-24 18:26 – Updated: 2026-03-26 19:52

Title

Parse Server: SQL injection via aggregate and distinct field names in PostgreSQL adapter

Summary

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.

Severity

8.6 (High)
