The miniOrange 2FA WordPress plugin versions before 6.2.8 contain a vulnerability that fails to properly limit the number of second-factor verification attempts. This flaw arises because the plugin tracks attempts against a client-supplied identifier that is reissued on every login, allowing an attacker who knows a user's password to repeatedly guess the one-time code without restriction and potentially take over the account.
AI Analysis
Technical Summary
CVE-2026-16619 describes a vulnerability in the miniOrange 2FA WordPress plugin prior to version 6.2.8. The plugin does not correctly enforce limits on the number of second-factor authentication attempts because it uses a client-supplied identifier that is refreshed on every login to track attempts. This design flaw enables an attacker with knowledge of a user's password to bypass rate limiting on one-time code verification, allowing unlimited guessing attempts and increasing the risk of account takeover.
Potential Impact
An attacker who has already obtained a user's password can exploit this vulnerability to bypass second-factor authentication protections by guessing the one-time verification code without limitation. This can lead to full account compromise, resulting in confidentiality, integrity, and availability impacts as indicated by the CVSS vector (Confidentiality: High, Integrity: High, Availability: High).
Mitigation Recommendations
A fix is available in miniOrange 2FA WordPress plugin version 6.2.8. Users should upgrade to version 6.2.8 or later to remediate this vulnerability. No other mitigation guidance is provided or necessary once the update is applied.
