CVE-2024-3570: Mintplexlabs Anythingllm

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

A stored Cross-Site Scripting (XSS) vulnerability exists in the chat functionality of the mintplex-labs/anything-llm repository, allowing attackers to execute arbitrary JavaScript in the context of a user's session. By manipulating the ChatBot responses, an attacker can inject malicious scripts to perform actions on behalf of the user, such as creating a new admin account or changing the user's password, leading to a complete takeover of the AnythingLLM application. The vulnerability stems from the improper sanitization of user and ChatBot input, specifically through the use of `dangerouslySetInnerHTML`. Successful exploitation requires convincing an admin to add a malicious LocalAI ChatBot to their AnythingLLM instance.
