A vulnerability exists in SimStudioAI versions through 0.6.92 within the Password Protection Handler component. The issue arises from an authentication token used in password-protected deployments, which is base64-encoded and not securely signed or bound to a server-side secret. This flaw allows for the creation of tokens that can bypass authentication, potentially leading to unauthorized access. The vulnerability can be exploited remotely, with a high complexity rating, although the exploitation appears to be challenging.
A pull request has been made to address this vulnerability by replacing the insecure token mechanism with HMAC-signed tokens. This PR is currently awaiting acceptance.
