CVE-2022-27780

Public on 2022-05-17
Modified on 2023-01-18
Description

A vulnerability was found in curl. This issue occurs because the curl URL parser wrongly accepts percent-encoded URL separators like / when decoding the hostname part of a URL, making it a different URL using the wrong hostname when it is later retrieved. This flaw allows a malicious actor to make circumventing filters.
