CVE-2026-42097 Details
Description
Sparx Pro Cloud Server requires authentication based on requested URL. An attacker can omit the "model" query parameter and send the model name only in the binary blob in POST request allowing SQL query execution without authentication. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
An authentication bypass vulnerability has been identified in Sparx Pro Cloud Server versions through 6.1. This vulnerability allows attackers to execute arbitrary SQL queries without authentication. The issue arises because the server's authentication mechanism relies on the requested URL, enabling attackers to omit the 'model' query parameter and instead send the model name within the binary blob of a POST request. As a result, unauthorized SQL query execution is possible.
