## Summary

DataRoom through 3.0.0 has an incorrect authorization flaw in its dataset test endpoint that lets a low-privileged visitor-role user remotely run arbitrary SQL SELECT queries against any configured relational data source, using that source's stored credentials. Because the attacker needs to be logged in but no user interaction is required, the bug can be reached over the network with only a visitor account.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- gcpaas DataRoom: through 3.0.0

## Description

DataRoom through 3.0.0 contains an incorrect authorization vulnerability in DatasetController.runTest that allows visitor-role users to execute dataset definitions supplied in the request body. Attackers can specify an arbitrary dataSourceCode and raw SELECT SQL to query any configured relational data source using its stored decrypted credentials, bypassing developer-only restrictions.

### What does this mean?

A user with visitor-role access can run arbitrary SELECT SQL queries against any configured relational data source, using that source's stored decrypted credentials. This lets them read data they should not be able to access.
