Description

microCLAUDIA in v3.2.0 and prior has an improper access control vulnerability. This flaw allows an authenticated user to perform unauthorized actions on other organizations' systems by sending direct API requests. To do so, the attacker can use organization identifiers obtained through a compromised endpoint or deduced manually. This vulnerability allows access between tenants, enabling an attacker to list and manage remote assets, uninstall agents, and even delete vaccines configurations.
