DeepChat: Incomplete Fix for CVE-2025-55733 leads to Remote Code Execution via Markdown Links bypassing `isValidExternalUrl`
Vulnerability Description
DeepChat is an open-source artificial intelligence agent platform that unifies models, tools, and agents. Prior to v1.0.4-beta.1, An incomplete mitigation for CVE-2025-55733 leaves DeepChat vulnerable to an arbitrary protocol execution bypass (RCE). While the patch correctly restricted api.openExternal() inside the renderer's preload/index.ts script, it structurally neglected to sanitize native Electron pop-up window handlers. An attacker or a compromised AI endpoint returning a Markdown link can trigger a target="_blank" native window interception in tabPresenter.ts, which forwards the malicious URL directly to shell.openExternal(url) and completely bypasses the isValidExternalUrl security boundary. This vulnerability is fixed in v1.0.4-beta.1.

输入验证不恰当
Vulnerability Title
DeepChat 输入验证错误漏洞
Vulnerability Description
DeepChat是ThinkInAIXYZ开源的一款智能助手。 DeepChat v1.0.4-beta.1之前版本存在输入验证错误漏洞,该漏洞源于对CVE-2025-55733的不完全缓解措施,虽然补丁正确限制了渲染器中的api.openExternal(),但结构上忽略了清理原生Electron弹出窗口处理程序,攻击者或受损AI端点返回的Markdown链接可触发target=_blank原生窗口拦截,将恶意URL直接转发给shell.openExternal(url)并完全绕过isValidExte
