parisneo/lollms-webui is vulnerable to a denial of service (DoS) attack due to uncontrolled resource consumption. Attackers can exploit the /open_code_in_vs_code and similar endpoints without authentication by sending repeated HTTP POST requests, leading to the opening of Visual Studio Code or the default folder opener (e.g., File Explorer, xdg-open) multiple times. This can render the host machine unusable by exhausting system resources. The vulnerability is present in the latest version 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.
