DiceBear is an avatar library for designers and developers. Prior to version 9.4.2, the function in used a regex-based approach to rewrite SVG / attributes, capping them at 2048px to prevent denial of service. This size capping could be bypassed by crafting SVG input that causes the regex to match a non-functional occurrence of before the actual SVG root element. When the SVG is subsequently rendered via on the Node.js code path, it renders at the attacker-specified dimensions, potentially causing out-of-memory crashes. In version 9.4.2, the regex-based approach has been replaced with XML-aware processing using to correctly identify and modify the SVG root element's attributes. Additionally, a constraint has been added to the call as defense-in-depth, ensuring the rendered output is always bounded regardless of SVG content.
