Published Updated By the CyberSecBulletin desk

CVE-2026-0405 is a high-severity improper authentication vulnerability in RBE970 from NETGEAR, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user.
