Can a WAF block it? Yes. The vulnerability involves cross-site scripting via SVG animate attributes, which are part of user input likely sent in HTTP requests. A WAF could partially detect unusual SVG animate attributes used maliciously, but distinguishing them from legitimate SVG content may be difficult. A custom WAF rule can filter SVG animate attributes in user input, but attackers can vary the request. No tracked WAF vendor has published a rule for this CVE yet.
