What is CVE-2026-78970?

JeecgBoot versions up to 3.9.2 are affected by an authorization bypass vulnerability in the SystemApiController component. This issue allows authenticated attackers to leverage any valid JWT token to access several API endpoints. By doing so, they can extract sensitive user information, including real names, phone numbers, email addresses, employee numbers, and role definitions. The vulnerability arises from the absence of robust permission checks and deficiencies in data desensitization, making it crucial for administrators to implement immediate security measures.
