CVE-2026-21833

LowCVSS 3.7/10Last modified Oct 2, 2026

Description

HCL AION is affected by a vulnerability in which the Content-Security-Policy (CSP) HTTP response header is not configured. CSP helps prevent attacks such as Cross-Site Scripting (XSS) by restricting the sources from which scripts, styles, and other resources can be loaded. The absence of this header may reduce the effectiveness of browser-based security controls, potentially resulting in unintended behavior or negative security impacts under certain conditions.
