CWE-80Published: May 6, 2026· Updated: May 7, 2026
Official Description
HCL DFXAnalytics is affected by an Insecure Security Header Configuration vulnerability where the application utilizes the outdated X-XSS-Protection header, which could allow an attacker to exploit browser-specific rendering flaws or bypass security controls that should instead be managed by a robust Content Security Policy (CSP).
Technical Analysis
CVE-2025-59854 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
