Other vulnerabilities in miniOrange 2FA WordPress plugin
See all- CVE-2026-77771High
The miniOrange 2FA WordPress plugin before 6.3.1 and before 19.3 does not scope its second-factor attempt limit to the account being attacked, keying it instead to a client-supplied identifier that can be changed at will. An attacker who already knows a victim's password can make unlimited one-time-passcode guesses and defeat the second factor. A second validation endpoint applies no attempt limit at all.
- CVE-2026-16619High
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, allowing an attacker who already knows a user's password to guess the one-time code without limit and take over the account.
- CVE-2026-16036High
The miniOrange 2FA WordPress plugin before 6.2.7 does not bind the second factor being configured during the pre-login two-factor challenge to the target account's existing factor, allowing an attacker who knows a user's password to rebind that user's second factor to an attacker-controlled destination, complete the challenge, and take over the account, including administrator accounts.
