Who should care

Users of SiYuan versions prior to 3.7.1 should apply the patch to prevent unauthorized access to sensitive information. This includes operators, administrators, and security teams responsible for managing and securing SiYuan deployments. Additionally, vulnerability management teams should review the affected scope and severity to prioritize patching.

Technical summary

The /snippets/*filepath route handler in SiYuan's kernel/server/serve.go file joins a single-decoded request path with the snippets directory without proper subpath containment or sensitive-path checks. This allows an authenticated request, such as /snippets/%2e%2e/%2e%2e/conf/conf.json, to read workspace secrets and the document database. The issue is fixed in version 3.7.1. The vulnerability has a CVSS score of 7.7.

Defensive priority

High

Recommended defensive actions

  • Apply the patch by updating SiYuan to version 3.7.1 or later.
  • Restrict access to the /snippets/*filepath route handler.
  • Monitor for suspicious activity related to the /snippets/*filepath route handler.
  • Review compensating controls for exposed systems while remediation is scheduled and verified.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
