dataCycle Public Markdown Path Traversal Via /docs/*path
CVE-2026-32820
Description
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, the documentation and static markdown renderer accepts attacker-controlled path segments and only runs them through the Rails HTML sanitizer, which does not remove directory traversal sequences. An unauthenticated attacker can traverse out of the intended docs or static directories and render arbitrary .md files from the application root or engine root. This is patched in version 26.06.08.
