Unauthenticated Super Admin access via session switching
Published Feb 24, 2026 · Updated Feb 24, 2026
Authentication bypass in DataLinkDC Dinky 1.2.0 through 1.2.5 allows remote attackers to gain Super Admin access through OpenAPI. In AppConfig.addInterceptors, the /openapi/** Sa-Token interceptor calls StpUtil.switchTo with the administrator ID when no login exists instead of rejecting the request. No credentials or user interaction are required; exposed endpoints can disclose SQL, submit tasks, or cancel Flink jobs with administrator authority.
