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
