AI Analysis
Technical Summary
CVE-2026-16619 describes a vulnerability in the miniOrange 2FA WordPress plugin before version 6.2.8 where the plugin does not correctly enforce limits on the number of second-factor verification attempts. The plugin tracks attempts against a client-supplied identifier that is reissued on every login, enabling an attacker with the user's password to bypass rate limiting on one-time code guesses and gain unauthorized access to the account.
Potential Impact
An attacker who has obtained a user's password can exploit this vulnerability to repeatedly guess the second-factor authentication code without limitation, increasing the likelihood of successful account compromise. This results in full account takeover, impacting confidentiality, integrity, and availability of the affected accounts.
Mitigation Recommendations
Upgrade the miniOrange 2FA WordPress plugin to version 6.2.8 or later, where this vulnerability is fixed. Versions prior to 6.2.8 are affected. No other mitigation or workaround is indicated.
