SVG XSS Attack Vectors

SVG (Scalable Vector Graphics) files can be weaponized to bypass web application security filters and execute malicious code. In the context of CVE-2025-68461, attackers embed JavaScript payloads within the values attribute of SVG animate tags, using keyTimes manipulation to force immediate execution. This technique bypasses traditional blacklist-based HTML sanitizers because the malicious code hides in what appears to be legitimate animation data. SVG-based XSS attacks are increasing in sophistication, targeting webmail clients, content management systems, and file-sharing platforms that allow vector graphics uploads or display.
