Allocation of Resources Without Limits or Throttling

CVE-2024-12537

High
7.5/10

Summary

In open-webui, the absence of authentication mechanisms allows any unauthenticated attacker to access the "api/v1/utils/code/format" endpoint. If a malicious actor sends a POST request with an excessively high volume of content, the server could become completely unresponsive. This could lead to severe performance issues, causing the server to become unresponsive or experience significant degradation, ultimately resulting in service interruptions for legitimate users. The issue affects open-webui versions prior to 0.5.13.
