Name of the Vulnerable Software and Affected Versions
SiYuan versions prior to 3.8.5
Description
Stored cross-site scripting occurs because the software fails to escape heading style attributes when rendering HTML for the outline and bookmark dock. Attackers can inject malicious style values by providing crafted notebooks or calling administrative endpoints. These values execute within the Electron renderer, potentially granting full system access.
Recommendations
Update SiYuan to version 3.8.5 or later.
