## Overview

Baserow versions 2.2.0 through 2.3.3 contain an SQL injection vulnerability in the index() formula function. A low-privileged authenticated user who can create or modify Formula fields can provide an undocumented fourth argument that is treated as a SQL template and interpolated directly into a PostgreSQL expression. The generated SQL executes through Baserow's database connection with the Baserow PostgreSQL role permissions, allowing data outside the user's workspace permissions to be read or modified.

## Affected

- `Baserow >= 2.2.0 <= 2.3.3`

## Remediation

Upgrade to Baserow 2.3.4 or later. The patch rejects user-supplied four-argument index() formulas and restricts legacy internal SQL templates to an allowlist. Verify the deployed version and run Formula-field regression tests before restoring Formula-field editing permissions.

### Workarounds

Until the upgrade is complete, restrict Formula-field creation and modification to trusted users. Identify Formula definitions containing a fourth index() argument, review database activity for unexpected SQL execution, and rotate database credentials if compromise is suspected.
