CVE-2025-68157— webpack buildHttp HttpUriPlugin allowedUris bypass via HTTP redirects

Quick assessment

Affected
webpack webpack
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Webpack是Webpack开源的一个模块打包器。它的主要目的是捆绑 JavaScript 文件以便在浏览器中使用，但它也能够转换、捆绑或打包几乎任何资源或资产。 Webpack 5.49.0至5.104.0之前版本存在代码问题漏洞，该漏洞源于当启用experiments.buildHttp时，HTTP(S)解析器在遵循HTTP 30x重定向后未重新验证allowedUris，可能导致策略或允许列表绕过，从而在构建时引发服务端请求伪造行为。

Vulnerability Title
webpack buildHttp HttpUriPlugin allowedUris bypass via HTTP redirects
Source: CVE Program / CVE List V5
Vulnerability Description
Webpack is a module bundler. From version 5.49.0 to before 5.104.0, when experiments.buildHttp is enabled, webpack’s HTTP(S) resolver (HttpUriPlugin) enforces allowedUris only for the initial URL, but does not re-validate allowedUris after following HTTP 30x redirects. As a result, an import that appears restricted to a trusted allow-list can be redirected to HTTP(S) URLs outside the allow-list. This is a policy/allow-list bypass that enables build-time SSRF behavior (requests from the build machine to internal-only endpoints, depending on network access) and untrusted content inclusion in build outputs (redirected content is treated as module source and bundled). This issue has been patched in version 5.104.0.
