Baserow vulnerabilities

Baserow 2.3.3 contains a 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 vulnerable expression is executed when Baserow recalculates formula field values, and the injected SQL runs with the privileges of the Baserow PostgreSQL role rather than the permissions of the authenticated application user.

Baserow dispatches an Application Builder data source without acting on the result of its permission check. The dispatch and record-name views are declared with a permission class that admits any caller, and the permission check does not halt execution. An unauthenticated request can receive rows and fields from the data source, and identifiers are small integers that can be enumerated. Version 2.3.1 passes raise_exception to the same call.

Baserow interpolates a user's display name into the rich-text mention markup without HTML encoding. PATCH /api/user/account/ stores the first_name value verbatim, and the mention renderer in web-frontend/modules/core/editor/mention.js builds its element with a template literal that places the name into a data-label attribute and the element body unescaped. A name containing a double quote closes that attribute and the opening tag, so following markup lands in the element content. The result is rendered through v-html by the rich-text field components, so any rich-text cell mentioning the account executes the stored script for every workspace member who views the table, without a click. Any workspace member, at the lowest permission level, can set the name and reach every other member of the workspace, and the payload persists until the name is changed or the mentioning row is removed. Version 2.3.0 escapes the value before interpolation.

Baserow up to version 2.3.2 has an issue in the BaserowImpersonateAuthTokenSerializer function within the Inactive Non-Staff User Handler component, leading to improper authorization. Remote exploitation is possible but requires high complexity. The maintainer suggests it may be more of a bug than a vulnerability, but recommends upgrading to 2.3.3.

Baserow up to version 2.3.2 has a vulnerability in the verify function in views.py of the 2FA Verify Endpoint component, leading to improper authentication. The attack can be launched remotely but has high complexity. The issue is fixed in version 2.3.3.
