# SiYuan: authenticated Reader users can read widget credential files

Link for people: https://infrastack.ai/live/CVE-2026-126264 (this .md is for agents)

SiYuan before 3.8.9 lets an authenticated user with the Reader role fetch credential-named widget files, such as credentials.json, by getting around the sensitive-path check in getFile. An attacker can collect API keys, tokens, and other stored secrets from those files.

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

## How to check

- Check the SiYuan version in use; affected if it is below `3.8.9`.
- Check whether any user accounts hold the Reader role and whether publish-referenced widgets store credentials.json files under the data/widgets directory.

## Fix

- SiYuan: upgrade to `3.8.9` or later.

## From the sources

SiYuan before 3.8.9 contains an information disclosure vulnerability that allows authenticated Reader users to retrieve credential-named widget files by bypassing the sensitive-path guard in getFile. Attackers can request paths like /data/widgets/<package>/credentials.json for publish-referenced widgets to obtain API keys, tokens, or other stored secrets.
