Is WP 2FA safe? Known vulnerabilities and latest version

The WP 2FA WordPress plugin before 4.2.0 does not perform an object-level capability check before removing a user's two-factor authentication configuration, allowing a site administrator on WordPress Multisite to remove the 2FA configuration of users outside their own site, including accounts they are not permitted to edit. On single-site installs an administrator can already manage all users, so this crosses a trust boundary only on Multisite.

Cross-Site Request Forgery (CSRF) vulnerability in Melapress WP 2FA wp-2fa allows Cross Site Request Forgery.This issue affects WP 2FA: from n/a through 4.1.0.

The WP 2FA WordPress plugin before 4.1.0 does not invalidate a time-based one-time passcode once it has been used, allowing an attacker who knows an account's password and has observed a valid code within its validity window to replay it and bypass two-factor authentication, including on administrator accounts.

The WP 2FA WordPress plugin before 4.1.0 does not validate the second authentication factor when one of its supported methods is selected at login, allowing an attacker who already knows a user's password to bypass two-factor authentication and fully access the account, including administrator accounts.

The WP 2FA WordPress plugin before 3.1.1.2 does not verify that the email address supplied during two-factor authentication setup belongs to the user, allowing an attacker who has obtained a user's credentials to redirect the setup verification code to an attacker-controlled email address and take over the account.

The WP 2FA WordPress plugin does not generate backup codes with enough entropy, which could allow attackers to bypass the second factor by brute forcing them

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Melapress WP 2FA wp-2fa.This issue affects WP 2FA: from n/a through <= 2.6.2.

The WP 2FA – Two-factor authentication for WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.0. This is due to missing or incorrect nonce validation on the send_backup_codes_email function. This makes it possible for unauthenticated attackers to send emails with arbitrary content to registered users via a forged request granted they can trick a site administrator or other registered user into performing an action such as clicking on a link. While a nonce check is present, it is only executed if a nonce is set. By omitting a nonce from the request, the check can be bypassed.

The WP 2FA – Two-factor authentication for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.5.0 via the send_backup_codes_email due to missing validation on a user controlled key. This makes it possible for subscriber-level attackers to email arbitrary users on the site.

The WP 2FA WordPress plugin before 2.3.0 uses comparison operators that don't mitigate time-based attacks, which could be abused to leak information about the authentication codes being compared.

The WP 2FA WordPress plugin before 2.2.1 does not sanitise and escape a parameter before outputting it back in an admin page, leading to a Reflected Cross-Site Scripting
