SiYuan: Stored XSS in imported .sy.zip content leads to arbitrary command execution

SiYuan is a personal knowledge management system. Prior to version 3.6.2, a vulnerability allows crafted block attribute values to bypass server-side attribute escaping when an HTML entity is mixed with raw special characters. An attacker can embed a malicious IAL value inside a .sy document, package it as a .sy.zip, and have the victim import it through the normal Import -> SiYuan .sy.zip workflow. Once the note is opened, the malicious attribute breaks out of its original HTML context and injects an event handler, resulting in stored XSS. In the Electron desktop client, this XSS reaches remote code execution because injected JavaScript runs with access to Node/Electron APIs. This issue has been patched in version 3.6.2.

SiYuan 代码注入漏洞

SiYuan是SiYuan开源的一个隐私至上的个人知识管理系统。 SiYuan 3.6.2之前版本存在代码注入漏洞，该漏洞源于特制块属性值可能绕过服务器端属性转义，导致存储型跨站脚本攻击，在Electron桌面客户端中可能进一步导致远程代码执行。
