Technical details
The sanitizeSvgContent() function parses custom SVG icon markup into a live DOM before filtering, creating a DOM-based XSS vulnerability. An attacker who can influence custom icon content can inject JavaScript that executes during icon creation, before unsafe elements are removed. This requires the ability to control icon markup parameters, such as through user input or application data flows that feed custom icons.
