SiYuan versions before 3.8.3 contain an SQL injection vulnerability in the graph.go query2Stmt function where tag values are concatenated raw into SQL string literals without escaping single quotes. A publish-mode reader or anonymous visitor can inject SQL via inline HTML span tags in the getGraph endpoint to execute arbitrary queries on the read-write database and exfiltrate private data across notebooks.
