A fix is available — apply it.

SiYuan versions before v3.7.4 contain an authentication bypass vulnerability in the FilterViewByPublishAccess filter that fails to check publish password protection when rendering attribute views and database rows. Unauthenticated readers can access password-protected document rows including titles, block IDs, and column values by calling renderAttributeView without supplying the required password.

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.
