Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

SiYuan (Go kernel, github.com/siyuan-note/siyuan/kernel) before 0.0.0-20260721043339-eef10568384e is vulnerable to SQL injection in the /api/filetree/searchDocs endpoint, where the search keyword is concatenated into a SQL statement without escaping. An unauthenticated attacker can exploit this when publish mode is enabled with auth disabled, or with a publish reader token, to read and modify content across all non-encrypted notebooks. The fix is to upgrade to 0.0.0-20260721043339-eef10568384e.
