CVE-2021-32696: Access of Resource Using Incompatible Type (Type Confusion)

The npm package striptags is an implementation of PHP’s strip_tags in Typescript. In striptags, a type-confusion vulnerability can cause striptags to concatenate unsanitized strings when an array-like object is passed in as the html parameter. This can be abused by an attacker who can control the shape of their input, e.g. if query parameters are passed directly into the function. This can lead to a XSS.
