CVE-2026-30869 Details
Description
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.
A path traversal vulnerability has been identified in SiYuan versions prior to 3.5.10, specifically within the '/export' endpoint. This vulnerability allows attackers to read arbitrary files from the server's filesystem. By exploiting double-encoded traversal sequences, sensitive files such as 'conf/conf.json' can be accessed. This configuration file contains critical secrets, including the API token, cookie signing key, and workspace access authentication code. Leaking these secrets may grant administrative access to the SiYuan kernel API and, in certain deployment scenarios, could be chained to achieve remote code execution.
Users should update to SiYuan version 3.5.10 or later, where this vulnerability has been fixed.
