An early warning has been issued for a potential information disclosure issue in the SiYuan package. Version v3.7.4-alpha.1 is reportedly affected.

What happened

The SiYuan package, specifically version v3.7.4-alpha.1, appears to expose the complete view structure of a database to anonymous readers. This exposure occurs via the /api/av/getAttributeViewFieldViews endpoint, which returns sensitive information including every view's name, icon, layout type, and per-field visibility flags. This issue is under investigation and has not been exploited in the wild as of the latest reports.

Users of the SiYuan package should assess their exposure by checking if they are using the affected version, v3.7.4-alpha.1. It is crucial to monitor the official sources for updates on this issue, as no official fix has been published yet.
