A fix is available — apply it.

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the resolveAssetPath endpoint that returns absolute filesystem paths unmodified to CheckAuth-only requests. Attackers can harvest relative asset paths from published documents and submit them to resolveAssetPath to obtain the server's absolute workspace path, disclosing the operating-system username and installation layout.

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
