Vulnerability Title
Inefficient RexExp complexity in generated code with .replace when transpiling named capturing groups
Vulnerability Description
Babel is a compiler for writing next generation JavaScript. When using versions of Babel prior to 7.26.10 and 8.0.0-alpha.17 to compile regular expression named capturing groups, Babel will generate a polyfill for the `.replace` method that has quadratic complexity on some specific replacement pattern strings (i.e. the second argument passed to `.replace`). Generated code is vulnerable if all the following conditions are true: Using Babel to compile regular expression named capturing groups, using the `.replace` method on a regular expression that contains named capturing groups, and the code using untrusted strings as the second argument of `.replace`. This problem has been fixed in `@babel/helpers` and `@babel/runtime` 7.26.10 and 8.0.0-alpha.17. It's likely that individual users do not directly depend on `@babel/helpers`, and instead depend on `@babel/core` (which itself depends on `@babel/helpers`). Upgrading to `@babel/core` 7.26.10 is not required, but it guarantees use of a new enough `@babel/helpers` version. Note that just updating Babel dependencies is not enough; one will also need to re-compile the code. No known workarounds are available.

Vulnerability Title
Babel 安全漏洞
Vulnerability Description
Babel是Babel开源的一个 JavaScript 的编译器。 Babel 7.26.10之前版本和8.0.0-alpha.17之前版本存在安全漏洞，该漏洞源于编译正则表达式命名捕获组时生成的.replace方法在某些特定替换模式字符串上具有二次复杂度，可能导致资源消耗增加。
