What is CVE-2026-32822?
CVE-2026-32822 is a medium-severity cross-site scripting vulnerability in datacycle-engine dataCycle-CORE, published on 20 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
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, any unauthenticated attacker can place arbitrary HTML into flash notifications on public routes and rely on the frontend toast component to inject that content into the DOM with `innerHTML`. This creates a reflected DOM XSS that can be delivered with a crafted link to a public page such as `/docs`. Because the vulnerable JavaScript is loaded by the normal application layout, the issue is not limited to a special debug page or an isolated admin-only view.
Weakness: CWE-80
