Description
Lobe Chat is an open-source artificial intelligence chat framework. Prior to version 1.129.4, there is a a cross-site scripting (XSS) vulnerability when handling chat message in lobe-chat that can be escalated to remote code execution on the user’s machine. In lobe-chat, when the response from the server is like <lobeArtifact identifier="ai-new-interpretation" ...> , it will be rendered with the lobeArtifact node, instead of the plain text. However, when the type of the lobeArtifact is image/svg+xml , it will be rendered as the SVGRender component, which internally uses dangerouslySetInnerHTML to set the content of the svg, resulting in XSS attack. Any party capable of injecting content into chat messages, such as hosting a malicious page for prompt injection, operating a compromised MCP server, or leveraging tool integrations, can exploit this vulnerability. This vulnerability is fixed in 1.129.4.

Executive Summary

This vulnerability is a cross-site scripting (XSS) issue in Lobe Chat versions prior to 1.129.4. It occurs when chat messages containing certain server responses with lobeArtifact nodes of type image/svg+xml are rendered using a component that dangerously sets inner HTML, allowing malicious SVG content to execute scripts. This can be exploited by anyone able to inject content into chat messages, potentially leading to remote code execution on the user's machine.

Impact Analysis

The vulnerability can lead to remote code execution on the user's machine if exploited. This means an attacker who can inject malicious content into chat messages could execute arbitrary code, potentially compromising the user's system, stealing data, or performing unauthorized actions.

Mitigation Strategies

Upgrade Lobe Chat to version 1.129.4 or later, as this version contains the fix for the cross-site scripting vulnerability. Additionally, restrict or monitor any parties capable of injecting content into chat messages, such as hosting malicious pages, compromised MCP servers, or tool integrations, to prevent exploitation.
