webpack — Vulnerabilities & Security Advisories 6

Webpack is a JavaScript module bundler primarily used for compiling and packaging web application assets. Historically, it has been susceptible to remote code execution (RCE) and cross-site scripting (XSS) vulnerabilities, often through improper handling of user input or malicious plugins. Notable security characteristics include its complex configuration system which can introduce misconfiguration risks. The project has addressed several critical vulnerabilities, including those allowing attackers to execute arbitrary code via crafted module requests. With six CVEs on record, security remains a concern, particularly in legacy versions where default configurations may expose applications to unnecessary risks.
