Description
SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the /api/block/getRefIDs endpoint that fails to check password-protected document tiers. Unauthenticated readers can discover that password-protected documents reference specific blocks and obtain block identifiers without entering the document password.
