Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- http4s is an open source scala interface for HTTP. In affected versions http4s is vulnerable to response-
splitting or request-splitting attacks when untrusted user input is used to create any of the following
fields: Header names (`Header.name`å), Header values (`Header.value`), Status reason phrases
(`Status.reason`), URI paths (`Uri.Path`), URI authority registered names (`URI.RegName`) (through 0.21).
This issue has been resolved in versions 0.21.30, 0.22.5, 0.23.4, and 1.0.0-M27 perform the following. As
a matter of practice http4s services and client applications should sanitize any user input in the
aforementioned fields before returning a request or response to the backend. The carriage return, newline,
and null characters are the most threatening. (CVE-2021-41084)
