## Technical details

Sparx Pro Cloud Server is vulnerable to incorrect authorization (CWE-863) within its database communication component. Due to a lack of sufficient permission checks, an authenticated user with low privileges can bypass intended restrictions to execute arbitrary SQL queries within the context of the database user. This allows for full read and write access to the repository data. The vulnerability was confirmed in version 6.1 (build 167) and earlier; the vendor has not provided details on a fix or the full range of affected versions.
