Detailsinfo

A vulnerability classified as critical has been found in Node.js up to 14.21.0/16.18.0/18.12.0/19.0.0 (JavaScript Library). This affects some unknown functionality of the component IsAllowedHost Handler. The manipulation with an unknown input leads to a os command injection vulnerability.
