CVE-2021-32696
Passing in a non-string 'html' argument can lead to unsanitized output
Impact
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.
