Answer in brief
CVE-2024-49393 records a Medium severity (CVSS 6.5) vulnerability in Mutt: neomutt: to and cc email header fields are not protected by cryptographic signing. The current sources do not mark it as known exploited. The current feed maps mutt (generic), Red Hat/mutt (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
