OPNsense 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 servicesntpdgps.php or servicesntpdpps.php to inject directives loaded by ntpd running as root.

OPNsense core before 26.7.8 contains a log injection vulnerability that allows unauthenticated attackers to plant victim IP addresses in the lockouthandler by submitting crafted WebGUI login usernames. Attackers can submit usernames like 'Invalid user <victim-ip>' repeatedly to add the victim to the sshlockout table, blocking SSH and WebGUI access and killing its pf states.
