Vulnerability Data
In Red Hat Advanced Cluster Security (RHACS), it was found that some security related HTTP headers were missing, allowing an attacker to exploit this with a clickjacking attack. An attacker could exploit this by convincing a valid RHACS user to…

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require implementing frame-ancestors / X-Frame-Options controls that prevent this weakness.

Security testing can detect missing frame protections, but does not itself implement the control.
Web filtering can block or sandbox untrusted frames, but does not enforce application-level frame-busting or CSP.
Application security requirements can mandate frame-ancestors / X-Frame-Options, directly addressing UI redressing risks.
Secure architecture principles include isolation of UI layers and proper use of browser security controls.
Secure coding practices directly require implementation of frame-busting headers or CSP frame-ancestors directives.
