Title
Open WebUI Affected by an External Model Server (Direct Connections) Code Injection via SSE Events
Summary
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Versions 0.6.224 and prior contain a code injection vulnerability in the Direct Connections feature that allows malicious external model servers to execute arbitrary JavaScript in victim browsers via Server-Sent Event (SSE) execute events. This leads to authentication token theft, complete account takeover, and when chained with the Functions API, enables remote code execution on the backend server. The attack requires the victim to enable Direct Connections (disabled by default) and add the attacker's malicious model URL, achievable through social engineering of the admin and subsequent users. This issue is fixed in version 0.6.35.
CWE
  • CWE-95 - Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')
  • CWE-829 - Inclusion of Functionality from Untrusted Control Sphere
  • CWE-830 - Inclusion of Web Functionality from an Untrusted Source
  • CWE-501 - Trust Boundary Violation
