Parse Server has SQL Injection through aggregate and distinct field names in PostgreSQL adapter
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | parse-server | >= 9.0.0, < 9.6.0-alpha.53 | 9.6.0-alpha.53 |
| npm | parse-server | < 8.6.59 | 8.6.59 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
