A fix is available — apply it.

SiYuan before v3.7.4 contains an information disclosure vulnerability in the /api/tag/getTag endpoint that returns tag labels and occurrence counts from password-protected documents to unauthenticated readers. Attackers can enumerate tag vocabulary and internal terminology from password-protected documents by calling the tag endpoint without providing the document's publish password.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (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.
