📄 Description (English)

SiYuan is a personal knowledge management system. Prior to version 3.6.2, the /api/file/readDir interface was used to traverse and retrieve the file names of all documents under a notebook. Version 3.6.2 patches the issue.

🤖 AI Executive Summary

SiYuan knowledge management system versions before 3.6.2 contain a directory traversal vulnerability in the /api/file/readDir interface that allows unauthorized access to file names within notebooks. This critical vulnerability (CVSS 9.8) enables attackers to enumerate and retrieve sensitive document information without proper authorization.

📄 Description (Arabic)
