zbateson mail-mime-parser before 3.0.9 and 4.x before 4.0.6 contains a CRLF header injection vulnerability in message-building helpers that fail to strip CR and LF characters. Attackers supplying crafted MIME type, charset, encoding, micalg, or protocol values can inject extra header lines such as a forged Bcc into outgoing messages.

CVE-2026-571548.1 ALT—
——0OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.11 and 26.4.1p1, authenticated Web UI or API users with delegated access to affected settings can submit CR or LF characters in fields expected to contain one line, causing generated privileged service configuration files to contain additional attacker-controlled directives or policy lines. The confirmed Dnsmasq path includes dhcp_boot.filename, dhcp_boot.servername, dhcp_boot.address, and dhcp_options.value, which are rendered into /usr/local/etc/dnsmasq.conf; access through page-services-dnsforwarder covers api/dnsmasq/*. Related affected fields span OpenVPN, DHCPv6, Unbound, IPsec, NTP, PPP or MPD, Monit, firewall, sudo, WebGUI, and System General configuration. Applying or restarting the affected service can alter behavior beyond the delegated setting, create service-side files, cross RBAC boundaries, or cause denial of service. Line injection through Monit mail password and adjacent Monit text fields into /usr/local/etc/monitrc demonstrated root command execution. Arbitrary shell command execution was not confirmed for the Dnsmasq path. This issue is fixed in versions 26.1.11 and 26.4.1p1.1dCVE-2026-1214323.5 BAJ—
——0AzuraCast before 0.24.0 contains a CRLF injection vulnerability that allows low-privilege station users to inject playlist entries by embedding CR/LF sequences in mount or remote relay display_name values. Attackers with Station:MountPoints or Station:RemoteRelays permission can inject FileN= and TitleN= lines into the public playlist.pls to redirect guest listeners to attacker-controlled streams under the victim station's name.1dCVE-2026-13575—60.8%
——18HTTP::Session versions before 0.54 for Perl allow memcached command injection via unfiltered session ids in HTTP::Session::Store::CHI.
The session id from the client's cookie reaches the CHI cache unchanged. The sibling HTTP::Session::Store::Memcached rejects ids that contain control characters, but the CHI store has no such check, and CHI does not escape keys for its memcached drivers.
With a memcached driver, a CR and LF in the session id end the cache command early, and the server reads the bytes after them as further commands.2dCVE-2026-1195605.9 MED28.0%
——8OPNsense core through 26.7.8 contains a configuration injection vulnerability that allows authenticated users to append ntpd.conf directives by embedding newlines in the fudge and refid fields. Attackers holding the page-services-ntp-gps or PPS privilege can submit CR/LF characters via services_ntpd_gps.php or services_ntpd_pps.php to inject directives loaded by ntpd running as root.5dCVE-2026-1194246.8 MED36.7%
——11OPNsense core before 26.7.8 contains a configuration line injection vulnerability that allows authenticated users with wireless-edit privilege to inject directives by embedding CR/LF characters in WPA fields. Attackers can place newlines in wpa.identity, wpa.passphrase, or RADIUS shared secrets to append arbitrary wpa_supplicant or hostapd directives loaded by root-run daemons.5dCVE-2026-1194173.7 BAJ39.3%
——12CakePHP 4.5.12, 4.6.5, 5.1.8 through 5.1.10, 5.2.14 through 5.2.15, 5.3.7, and 5.4.0 through 5.4.3 contain an email header injection vulnerability because SmtpTransport and MailTransport strip only CRLF pairs from header values, an incomplete fix for CVE-2026-77634. Attackers controlling custom headers set via Message::setHeaders() or Message::addHeaders() can insert a bare CR or LF to inject headers like Bcc, redirecting or altering outgoing mail.5d
