What changed? Why?
We discovered a DOM Clobbering vulnerability in Webpack’s
AutoPublicPathRuntimeModule. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., animgtag with an unsanitizednameattribute) are present.We found the real-world exploitation of this gadget in the Canvas LMS which allows XSS attack happens through an javascript code compiled by Webpack (the vulnerable part is from Webpack). We believe this is a severe issue. If Webpack’s code is not resilient to DOM Clobbering attacks, it could lead to significant security vulnerabilities in any web application using Webpack-compiled code.
