Vulnerability Details

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 Details

PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. Versions prior to 8.5.10 do not escape "</style>" sequences when stringifying CSS ASTs. When user-submitted CSS is parsed and re-stringified for embedding in HTML "<style>" tags, "</style>" in CSS values breaks out of the style context, enabling XSS. Version 8.5.10 fixes the issue.
