# SiYuan: TLS Private Keys Readable via getFile (Incomplete Blocklist) in github.com/siyuan-note/siyuan/kernel

SiYuan's getFile endpoint can read TLS private key files because its path blocklist is incomplete. An attacker who can reach the API can obtain the server's TLS private key.

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