CVE-2026-111283 - CRITICAL Severity Vulnerability

BMC Helix Network Management on-prem 26.3.00 before 26.3.01 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as the local administrator with any password when SAML single sign-on is configured. Attackers can submit the administrator username with an arbitrary password on the web login page to obtain a SuperAdmin session, modify device credentials, run device commands, and alter audit records.

CVE-2026-107808

CVE-2026-107808 - HIGH Severity Vulnerability

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, POST /api/login checks EnabledOTP but does not require a WebAuthn assertion when EnabledPasskey is true and no TOTP secret is configured. A passkey-only account is therefore issued a session after password verification, despite Enabled2FA reporting that the account has a second factor. An attacker who obtains the password can take over the account and reach administrative functionality without the registered passkey. This issue is fixed in version 2.5.0.
