Name of the Vulnerable Software and Affected Versions: Mutt versions prior to 1.14.3
Description: The issue is related to insufficient data protection in the Mutt email client, allowing a remote attacker to perform a man-in-the-middle attack. Specifically, Mutt before version 1.14.3 is vulnerable to an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response.
Recommendations: For versions prior to 1.14.3, update to version 1.14.3 or later to resolve the issue. As a temporary workaround, consider disabling the IMAP fcc/postpone feature until a patch is available. Restrict access to sensitive email accounts to minimize the risk of exploitation. Avoid using the PREAUTH response in IMAP connections until the issue is resolved.
