What is CVE-2025-68157?

In Webpack versions from 5.49.0 to just before 5.104.0, a critical vulnerability exists where the HTTP(S) resolver fails to revalidate allowed URIs post-30x redirects. This failure potentially allows an attacker to bypass the configured allow-list, enabling the inclusion of untrusted content in build outputs. Consequently, it may lead to SSRF behavior from the build environment, impacting internal network security. This issue has been addressed in version 5.104.0.
