CVE-2025-55674: Apache Superset: Improper SQL authorisation, parse not checking for specific engine functions

[Daniel Gaspar <dpgaspar () apache org>]

Severity: 

Affected versions:

- Apache Superset before 5.0.0

Description:

A bypass of the DISALLOWED_SQL_FUNCTIONS security feature in Apache Superset allows for the execution of blocked SQL 
functions. An attacker can use a special inline block to circumvent the denylist. This allows a user with SQL Lab 
access to execute functions that were intended to be disabled, leading to the disclosure of sensitive database 
information like the software version.

This issue affects Apache Superset: before 5.0.0.

Users are recommended to upgrade to version 5.0.0, which fixes the issue.
