Recent Neomutt Security Vulnerabilities
Mutt and NeoMutt Email Header Spoofing Vulnerability
CVE-2024-49394
5.3 - Medium
- November 12, 2024
In mutt and neomutt the In-Reply-To email header field is not protected by cryptographic signing which allows an attacker to reuse an unencrypted but signed email message to impersonate the original sender.

Mutt and NeoMutt PGP Encryption Bcc Header Leak Vulnerability
CVE-2024-49395
5.3 - Medium
- November 12, 2024
In mutt and neomutt, PGP encryption does not use the --hidden-recipient mode which may leak the Bcc email header field by inferring from the recipients info.

CVE-2024-49393
5.9 - Medium
- November 12, 2024
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.
Improper Verification of Cryptographic Signature
Mutt 1.11.0 through 2.0.x before 2.0.7 (and NeoMutt 2019-10-25 through 2021-05-04) has a $imap_qresync issue in
CVE-2021-32055
9.1 - Critical
- May 05, 2021
Mutt 1.11.0 through 2.0.x before 2.0.7 (and NeoMutt 2019-10-25 through 2021-05-04) has a $imap_qresync issue in which imap/util.c has an out-of-bounds read in situations where an IMAP sequence set ends with a comma. NOTE: the $imap_qresync setting for QRESYNC is not enabled by default.
Out-of-bounds Read
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure
CVE-2020-28896
5.3 - Medium
- November 23, 2020
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.
Insufficiently Protected Credentials
