Vulnerability Title
webpack buildHttp HttpUriPlugin allowedUris bypass via HTTP redirects
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.

服务端请求伪造(SSRF)
Vulnerability Title
Webpack 代码问题漏洞
Vulnerability Description
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。
