Summary

SiYuan versions before v3.7.3 contain SQL injection vulnerabilities in the fullTextSearchAssetContent endpoint reachable by unauthenticated users and publish RoleReader tokens. Attackers can execute arbitrary SQL on the read-write asset-content database via unescaped method parameters and REGEXP clauses to read, modify, or delete cross-notebook data.
