SQL Injection in Siyuan-Note Siyuan
CVE-2026-69085
SiYuan before v3.7.3 contains a SQL injection vulnerability in the /api/filetree/searchDocs endpoint, where the caller-supplied keyword parameter is concatenated directly into SQL statements with no escaping or parameter binding. The endpoint is reachable by a publish RoleReader token, or unauthenticated when publish mode is enabled with Publish.Auth.Enable set to false. Because the statement executes on a read-write SQLite handle via a driver that supports stacked (semicolon-separated) statements, an attacker can read and modify database content across all cleartext (non-encrypted) notebooks on the instance.
