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.

- GHSA-p2w6-rmh7-w8q3Parse Server has SQL Injection through aggregate and distinct field names in PostgreSQL adapter2026-03-24ghsa · osvUS
### 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.
