Title
OPNsense before 26.7.8 Wireless WPA Configuration Line Injection via Identity
Summary
OPNsense 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.
