CVE-2026-32820Network attack vector

Unauthenticated Markdown file disclosure via path traversal

Published Jul 20, 2026 · Updated Jul 20, 2026

Path traversal in dataCycle CORE 25.07.3 and earlier allows remote attackers to read Markdown files through public rendering routes. The documentation and static Markdown renderer sanitizes attacker-controlled path segments as HTML instead of constraining the resolved path to its docs or static root. No authentication or user interaction is required, and disclosure is limited to reachable .md files under the application or engine root.
