CVE-2026-16035: CWE-862 Missing Authorization in miniOrange 2FA
The miniOrange 2FA WordPress plugin before 6.2.7 does not restrict who can trigger its second-factor configuration OTP send, nor bind the OTP recipient to the enrolling user's own address, allowing a low-privileged user to send one-time-passcode emails to arbitrary recipients and to exhaust the site's metered OTP allowance, preventing legitimate users from receiving their second-factor codes.
AI Analysis
Technical Summary
CVE-2026-16035 is a missing authorization vulnerability (CWE-862) in the miniOrange 2FA WordPress plugin prior to version 6.2.7. The plugin does not restrict which users can trigger the sending of second-factor OTP emails, nor does it bind the OTP recipient to the enrolling user's email address. As a result, a low-privileged user can send OTP emails to arbitrary recipients and exhaust the site's metered OTP allowance, disrupting legitimate second-factor authentication processes.
Potential Impact
An attacker with low privileges can abuse the OTP sending functionality to send one-time passcodes to arbitrary email addresses and deplete the site's OTP quota. This can lead to denial of service for legitimate users who rely on receiving OTPs for two-factor authentication, potentially preventing them from logging in securely.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the OTP sending functionality to trusted users only, if possible, and monitor for abuse of OTP sending features.
