Description Preview
Babel, a compiler for next-generation JavaScript, has a vulnerability in versions prior to 7.26.10 and 8.0.0-alpha.17. When these versions are used to compile regular expression named capturing groups, Babel generates a polyfill for the `.replace` method that has quadratic complexity on some specific replacement pattern strings. The generated code is vulnerable if all the following conditions are met: 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 vulnerability has been fixed in `@babel/helpers` and `@babel/runtime` 7.26.10 and 8.0.0-alpha.17.
Overview
The vulnerability is related to inefficient RegExp complexity in generated code with .replace when transpiling named capturing groups. It has a base score of 6.2 and a base severity of medium. The attack complexity is low and the attack vector is local. The availability impact is high, while the confidentiality and integrity impacts are none.
Remediation
The problem has been fixed in @babel/helpers and @babel/runtime 7.26.10 and 8.0.0-alpha.17. Users are advised to upgrade to these versions. Note that just updating Babel dependencies is not enough; one will also need to re-compile the code. No known workarounds are available.
