Snyk provides a comprehensive approach to developer security by securing critical components of the software supply chain, application security posture management (ASPM), AI-generated code, and more. We recognize the increasing risk of exposed secrets in the cloud, so we’ve tapped Nightfall AI to provide a critical feature for developer security: advanced secrets scanning.

Snyk's security researchers have conducted some research to better understand the risks of WebExtensions, both well-known (i.e. XSS, code injection) and those more specific to WebExtensions themselves. From our research we identified and disclosed some vulnerabilities within some popular browser extensions: React Developer Tools and Vue.js devtools. In this post, we will explore the WebExtension technology and look into the vulnerabilities identified.

Modern applications are designed to process, use and store vast amounts of sensitive data. As adversaries seek to infiltrate these applications, IT and security teams must ensure the software they use has the strongest possible security. The first step to implementing strong application security is understanding the type of application you need to protect. The two types of applications security teams must be familiar with are custom-developed software and commercial off-the-shelf (COTS) software.
