CVE-2026-77771: Unknown Miniorange 2fa

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

The miniOrange 2FA WordPress plugin before 6.3.1, miniOrange 2FA WordPress plugin before 19.3 does not scope its second-factor attempt limit to the account being attacked, keying it instead to an identifier the client supplies and can change at will, allowing an attacker who already knows a victim's password to make unlimited one-time-passcode guesses and defeat the second factor. A second validation endpoint applies no attempt limit at all.

Affected products

• Unknown Miniorange 2fa: from 6.2.8, before 6.3.1 (fixed in 6.3.1); from 18.0, before 19.3 (fixed in 19.3)
