A vulnerability in mintplex-labs/anything-llm allows for a denial of service (DoS) condition through the modification of a users id attribute to a value of 0. This issue affects the current version of the software, with the latest commit id 57984fa85c31988b2eff429adfc654c46e0c342a. By exploiting this vulnerability, an attacker, with manager or admin privileges, can render a chosen account completely inaccessible. The applications mechanism for suspending accounts does not provide a means to reverse this condition through the UI, leading to uncontrolled resource consumption. The vulnerability is introduced due to the lack of input validation and sanitization in the user modification endpoint and the middlewares token validation logic. This issue has been addressed in version 1.0.0 of the software.
The product does not properly control the allocation and maintenance of a limited resource.

Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
