  "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 `\u003c/style\u003e` sequences when stringifying CSS ASTs. When user-submitted CSS is parsed and re-stringified for embedding in HTML `\u003cstyle\u003e` tags, `\u003c/style\u003e` in CSS values breaks out of the style context, enabling XSS. Version 8.5.10 fixes the issue.",
