Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - SiYuan is a personal knowledge management system. Prior to version 3.6.2, a malicious website can achieve
 Remote Code Execution (RCE) on any desktop running SiYuan by exploiting the permissive CORS policy

 next time the user opens SiYuan's UI. No user interaction is required beyond visiting the malicious
 website while SiYuan is running. This issue has been patched in version 3.6.2. (CVE-2026-34449)
