What is CVE-2026-32820?
CVE-2026-32820 is a high-severity path traversal vulnerability in datacycle-engine dataCycle-CORE, published on 20 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-22
