The Subscribe to Comments WordPress plugin before 2.3.3 does not sanitise newline characters from a notification sender-name setting before using it in e-mail headers, allowing users with Author-level access and above to inject arbitrary e-mail headers, such as a hidden Bcc, and to spoof the sender.

CVE-2026-109683——
——0A newline
injection vulnerability exists in the UPnP service of Archer BE805 v1 such that
an adjacent attacker can supply newline characters in a UPnP port-mapping
description due to improper sanitization, resulting in possible injection of unintended
content into UPnP port-mapping data.
Successful
exploitation may allow an unauthenticated attacker on the local network to
modify runtime UPnP port-mapping information and create spoofed entries within
the affected service. The issue is limited to the integrity of UPnP mapping
data and does not demonstrate code execution or privilege escalation.22hCVE-2026-1232985.0 MÉD—

——13mpv 0.29.0 before 0.42.0 contains a playlist injection vulnerability in the bundled ytdl_hook script that allows remote attackers to add unchecked entries by embedding newlines in playlist URLs. Attackers controlling a feed or page can bypass url_is_safe() to open file:// or av:// inputs, reading local files or loading shared objects via ladspa for code execution.2dCVE-2026-1219467.2 ALT25.7%
——8zbateson 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.3dCVE-2026-571548.1 ALT40.1%
——12OPNsense 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 26.4.1p1.15hCVE-2026-1214323.5 BAI8.8%
——3AzuraCast 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.4d
