CVE-2026-32822 in dataCycle-CORE
Summary
by MITRE • 07/20/2026
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.

This vulnerability exists within dataCycle-CORE version 25.07.3 and earlier, where the system fails to properly sanitize user input in flash notifications that are displayed to all users regardless of authentication status. The flaw occurs when unauthenticated attackers can inject arbitrary HTML content into flash notifications that are then rendered on public routes such as the documentation page at /docs. The vulnerability stems from the frontend toast component's improper handling of user-provided data through direct DOM manipulation using innerHTML, which allows malicious scripts to execute in the context of the victim's browser session.
The technical implementation of this vulnerability demonstrates a classic reflected cross-site scripting flaw that operates at the DOM level rather than traditional server-side injection. When users navigate to public pages where flash notifications are displayed, any HTML content injected by an attacker through the notification system gets parsed and executed directly in the browser without proper sanitization or context-aware escaping. This particular implementation is especially concerning because it leverages the standard application layout that loads across all public routes, making the vulnerability pervasive rather than isolated to specific debug or admin interfaces.
The operational impact of this vulnerability extends beyond simple XSS exploitation as it provides attackers with the ability to execute arbitrary JavaScript code in victims' browsers with the privileges of the logged-in user. Attackers can craft malicious links that, when clicked by users accessing public pages, inject malware, steal session cookies, perform unauthorized actions on behalf of users, or redirect them to phishing sites. The vulnerability's persistence across all public routes means that any authenticated user visiting a compromised page could be exploited, and the attack vector is easily scalable as attackers can distribute malicious links through various channels without requiring specific user interaction beyond clicking the crafted link.
This vulnerability maps directly to CWE-79 which defines Cross-Site Scripting flaws where input data is not properly sanitized before being rendered in web pages. The implementation pattern aligns with ATT&CK technique T1566.001 which covers "Phishing via Social Media" and T1584.002 for "Compromise Software Supply Chain" as attackers can leverage this vulnerability to deliver malicious payloads through social engineering campaigns targeting public documentation pages. The widespread nature of the affected routes means that any user visiting public pages could be compromised, making this a critical security issue requiring immediate remediation.
The recommended mitigations include implementing strict input validation and output encoding for all user-provided content in flash notifications, utilizing a Content Security Policy to prevent inline script execution, and replacing direct innerHTML manipulation with safer DOM methods such as textContent or document.createElement. Additionally, the system should employ proper sanitization libraries that can strip malicious HTML tags and attributes before rendering any user-generated content, ensuring that all notification systems follow secure coding practices and that no untrusted data is directly injected into the DOM without proper context-aware escaping mechanisms.
