What is CVE-2026-110773?

GrowChief version 0.3.0 contains a vulnerability in the getAllUsers handler, where missing authorization checks enable authenticated users to list all users across different organizations. This oversight allows attackers, even with low privileges such as self-registered accounts, to exploit the GET /users/all-users endpoint. By sending minimal query parameters, such as an empty string, they can retrieve sensitive information, including user IDs, emails, names, and organization IDs belonging to all tenants within the system. This flaw poses significant privacy and security risks, making it critical for users to implement protective measures.
