description

SiYuan versions before 3.8.5 can expose protected database-row data through export previews. A publish reader who can access a public document containing a database view may retrieve data from password-protected or publish-disabled rows.

mitigation

Upgrade SiYuan to version 3.8.5 or later. Restrict publish-reader access to public documents containing database views until the upgrade is complete.

fixed in v3.8.5
