CVE-2022-31124 is a high-severity flaw (CVSS 7.7) affecting openssh key parser. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

openssh_key_parser is an open source Python package providing utilities to parse and pack OpenSSH private and public key files. In versions prior to 0.0.6 if a field of a key is shorter than it is declared to be, the parser raises an error with a message containing the raw field value. An attacker able to modify the declared length of a key's sensitive field can thus expose the raw value of that field. Users are advised to upgrade to version 0.0.
