CVE-2026-30869— SiYuan has a Path Traversal in /export Endpoint Allows Arbitrary File Read and Secret Leakage

SiYuan has a Path Traversal in /export Endpoint Allows Arbitrary File Read and Secret Leakage

SiYuan is a personal knowledge management system. Prior to 3.5.10, a path traversal vulnerability in the /export endpoint allows an attacker to read arbitrary files from the server filesystem. By exploiting double‑encoded traversal sequences, an attacker can access sensitive files such as conf/conf.json, which contains secrets including the API token, cookie signing key, and workspace access authentication code. Leaking these secrets may enable administrative access to the SiYuan kernel API, and in certain deployment scenarios could potentially be chained into remote code execution (RCE). This vulnerability is fixed in 3.5.10.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

对路径名的限制不恰当(路径遍历)

SiYuan 安全漏洞

SiYuan是SiYuan开源的一个隐私至上的个人知识管理系统。 SiYuan 3.5.10之前版本存在安全漏洞，该漏洞源于/export端点存在路径遍历，可能导致读取服务器文件系统中的任意文件，泄露敏感配置信息。
