CVE-2026-42100
Improper Handling of Syntactically Invalid Structure in Sparx Pro Cloud Server allows Denial of Service (DoS) attack to be executed by sending an specially crafted SQL query. This causes the Pro Cloud Server service to terminate unexpectedly.
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.
