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.
