Affected packages

• npm striptags: < 3.2.0 → fixed in 3.2.0

Description

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. Impact XSS Patches `3.2.0` Workarounds Ensure that the `html` parameter is a string before calling the function.
