# SiYuan: /history/*path and /repo/diff/*path potentially exposing historical snapshots of data/.siyuan/publishAccess.json and data/templates/* in github.com/siyuan-note/siyuan/kernel

SiYuan's kernel exposes history and repo diff endpoints that can return historical snapshots of data/.siyuan/publishAccess.json and data/templates/* files. An attacker who can reach those endpoints can read past versions of publish access settings and templates.

_Summary, check and fix written by a model from the sources; labelled as such._
