description

SiYuan on Windows is affected by a path validation bypass in sensitive-path checks. An attacker able to submit import requests can cause protected local files or directories to be imported into publicly accessible assets by using Windows extended-length path syntax. Exposure depends on the affected service accepting those requests and having access to the targeted files.

mitigation

Upgrade siyuan-note/siyuan to v3.8.7. Until upgraded, restrict access to the SiYuan service and prevent untrusted users from invoking import functionality.

fixed in v3.8.7
