CVE-2024-49393
In neomutt and mutt, the To and Cc email headers are not validated by cryptographic signing which allows an attacker that intercepts a message to change their value and include himself as a one of the recipients to compromise message confidentiality.
Does this matter?
Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.
