CVE-2026-42098 is an authorization bypass in Sparx Enterprise Architect caused by reliance on client-side enforcement of role-based restrictions. According to the provided content, Enterprise Architect includes a security feature intended to limit user actions based on assigned roles, but an authenticated attacker can modify the client application's behavior, for example by using a debugger or patching the binary, and then log in as any other user, including an administrator. This indicates that authorization and identity trust decisions are improperly delegated to the client rather than being robustly enforced server-side or repository-side. Versions 17.1 and below were tested and confirmed vulnerable; other versions were not tested and may also be affected.
