What is CVE-2025-68458?

A policy/allow-list bypass vulnerability has been identified in Webpack, affecting versions from 5.49.0 to before 5.104.1. When the experiments.buildHttp feature is enabled, attackers can exploit the HttpUriPlugin to bypass the HTTP(S) resolver. This may allow unauthorized access to resources from external hosts by crafting specific URLs that include user credentials. The vulnerability exploits inadequate string prefix checks in allowUris enforcement, potentially leading to SSRF attacks and the inclusion of untrusted content during the build process. The issue has been rectified in version 5.104.1.
