Package	Ecosystem	Affected	Fixed in
github.com/siyuan-note/siyuan/kernel	Go	<0.0.0-20260704035518-d0f0fe146fb0	0.0.0-20260704035518-d0f0fe146fb0

Machine-written summary

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

Siyuan's block search endpoint (fullTextSearchBlock) builds SQL from attacker-controlled paths[] values, affecting Go module github.com/siyuan-note/siyuan/kernel at versions before 0.0.0-20260704035518-d0f0fe146fb0. Through the publish service, an unauthenticated visitor can inject SQL that returns block content from hidden documents, because the publish access filter checks only the returned box and path. An attacker can read private note content that publish visibility controls are meant to hide. Upgrade to 0.0.0-20260704035518-d0f0fe146fb0 or later.
