sometimes truncated by one byte during IMAP auth_cram MD5 digest authentication, potentially causing authentication failures or security issues.(CVE-2026-43860)\n\nmutt before 2.3.2 does not check for '\\0' in url_pct_decode, resulting in improper null byte handling vulnerability.(CVE-2026-43861)\n\nIn mutt before version 2.3.2, the imap_auth_gss security level is mishandled, which may lead to
