The WebExtension technology is a browser extension API that allows developers to create cross-browser extensions for Firefox, Chrome, and others. However, there are inherent risks involved with this technology, including unverified external messages, forwarding unverified external messages, and unauthorized access to page capture APIs. Researchers have identified vulnerabilities in popular browser extensions such as React Developer Tools and Vue.js devtools, which can be exploited by malicious actors to generate clicks, steal sensitive resources, or leak screenshot data back to the malicious web page. These vulnerabilities highlight the importance of staying on top of emerging risks and integrating WebExtension technology into applications without sacrificing security.
