Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
SiYuan kernel (Go module github.com/siyuan-note/siyuan/kernel) versions before 0.0.0-20260510110132-b763d787d1f2 are affected by a path traversal in the /export/temp/ request branch of the file-serving handler, which skips the sensitive-file and subpath checks added by an earlier fix. An authenticated user can request crafted paths to read arbitrary files on the server, such as system files or SiYuan workspace data. Upgrade to 0.0.0-20260510110132-b763d787d1f2 or later.
