A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or cookie header data on HTTP redirects to the same host but another port number.(CVE-2022-27776)

curl < 7.84.0 supports 'chained' HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable 'links' in this 'decompression chain' was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a 'malloc bomb', makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.(CVE-2022-32206)

When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.(CVE-2022-32208)");
