Technical details
The vulnerability is a client-side request validation bypass in Web Dynpro Java's styling resource resolution mechanism. An unauthenticated attacker can craft a malicious URL that, when clicked by an authenticated user, causes the victim's browser to load attacker-controlled styling resources within the trusted application context, enabling UI redressing (clickjacking/phishing) and limited content exfiltration. The attack requires user interaction (clicking a link) but no prior authentication by the attacker.
