An SVG Filter is a feature in Scalable Vector Graphics (SVG) that applies visual effects - such as blur, shadow, or color adjustments - to images or graphic elements. These filters are defined using XML and can be combined to create complex visual transformations. In cybersecurity contexts, SVG filters can also be used to perform logic operations within images, which may have implications for security and data processing. Understanding SVG filters is important for both web design and recognizing potential security vulnerabilities.
