CVE-2025-15624Network attack vector

Credential exposure via plaintext generated-password storage

Published Apr 17, 2026 · Updated Apr 17, 2026

Plaintext password storage in Sparx Systems Pro Cloud Server 6.0.163 allows remote attackers to obtain locally generated credentials. When OpenID is the primary Enterprise Architect authentication method, the server creates a local password for each user and writes it to storage without encryption or hashing. The flaw is present only with this OpenID configuration, and the public record does not identify the storage location or retrieval request.
