SonicWall rolled out fixes for three SonicOS vulnerabilities, urging customers to immediately patch their Gen 6, Gen 7, and Gen 8 firewalls. The high-severity flaw, tracked as CVE-2026-0204, allows to bypass access controls and access certain management interface functions, SonicWall notes in an advisory. An attacker with access to the management interface could potentially modify firewall configurations and disable security protections. The medium-severity vulnerabilities CVE-2026-0205 and CVE-2026-0206 could be exploited to bypass security restrictions and crash vulnerable firewalls. Fixes were included in firmware releases 6.5.5.2-28n, 7.3.2-7010, and 8.2.0-8009.
