CVE-2026-16619 miniOrange CVE debrief

The miniOrange 2FA WordPress plugin before 6.2.8 does not correctly limit the number of second-factor verification attempts, tracking them against a client-supplied identifier that is reissued on every login. This allows an attacker who already knows a user's password to guess the one-time code without limit and take over the account. The vulnerability affects WordPress sites using the miniOrange 2FA plugin, particularly those with multiple users and administrative access. Evidence is limited; primary official records indicate a vulnerability in the miniOrange 2FA WordPress plugin before 6.2.8. Verification of affected scope and vendor remediation is needed.
