Vulnerability Title
Lobe Chat has Cross-Site Scripting (XSS) issue that may escalate to Remote Code Execution (RCE)
Source: CVE Program / CVE List V5
Vulnerability Description
LobeChat is an open source chat application platform. Prior to version 2.0.0-next.180, a stored Cross-Site Scripting (XSS) vulnerability in the Mermaid artifact renderer allows attackers to execute arbitrary JavaScript within the application context. This XSS can be escalated to Remote Code Execution (RCE) by leveraging the exposed `electronAPI` IPC bridge, allowing attackers to run arbitrary system commands on the victim's machine. Version 2.0.0-next.180 patches the issue.
