CVE-2025-67744
CriticalSummary
DeepChat before version 0.5.3 contains an XSS vulnerability in the Mermaid diagram rendering component, which escalates to full Remote Code Execution (RCE) due to the exposure of the Electron IPC renderer to the DOM. An attacker can execute arbitrary system commands.
Risk Assessment
The risk is critical because an attacker can take over the user's system by executing arbitrary commands, potentially leading to data theft or full compromise.
Recommendation
Immediately upgrade DeepChat to version 0.5.3 or later, which includes a patch.
Original NVD description (English source)
DeepChat is an open-source artificial intelligence agent platform that unifies models, tools, and agents. Prior to version 0.5.3, a security vulnerability exists in the Mermaid diagram rendering component that allows arbitrary JavaScript execution. Due to the exposure of the Electron IPC renderer to the DOM, this Cross-Site Scripting (XSS) flaw escalates to full Remote Code Execution (RCE), allowing an attacker to execute arbitrary system commands. Two concurrent issues, unsafe Mermaid configuration and an exposed IPC interface, cause this issue. Version 0.5.3 contains a patch.
