Title
SiYuan before v3.8.2 Private Attribute View Key Enumeration
Summary
SiYuan versions before v3.8.2 contain an information disclosure vulnerability in the getAttributeViewKeysByID endpoint that allows publish readers to enumerate private attribute view key definitions without verifying parent database visibility. Attackers can access the endpoint to retrieve complete key schemas including sensitive field names and relation definitions from hidden databases.

Title
BookWyrm through 0.9.1 Missing Authorization on the Favorite and Unfavorite Endpoints
Summary
BookWyrm through 0.9.1 fails to validate user visibility permissions in the Favorite and Unfavorite views, allowing authenticated attackers to favorite or unfavorite followers-only and direct statuses they cannot access. Attackers can POST to the favorite endpoint with a status ID to create unauthorized interactions, trigger ActivityPub broadcasts, and enumerate private status IDs through response differentiation.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
No CAPEC attack patterns related to this CWE.
