Description
HCL AION is affected by a vulnerability where the Content-Security-Policy (CSP) security response header was missing from application responses. Without this header, the browser does not restrict the sources of scripts and other content, increasing exposure to cross-site scripting and content-injection attacks, potentially resulting in unintended behavior or security impact under certain conditions.
