CVE-2026-16035: CWE-862 Missing Authorization in miniOrange 2FA
miniOrange 2FA WordPress plugin versions before 6.2.7 have a missing authorization vulnerability that allows low-privileged users to trigger second-factor OTP emails to arbitrary recipients. This flaw can be exploited to exhaust the site's OTP sending quota, potentially blocking legitimate users from receiving their second-factor authentication codes.
AI Analysis
Technical Summary
The miniOrange 2FA WordPress plugin prior to version 6.2.7 does not properly restrict which users can initiate the sending of second-factor OTP emails, nor does it bind the OTP recipient to the enrolling user's email address. This missing authorization (CWE-862) enables low-privileged users to send OTP emails to arbitrary recipients and exhaust the site's metered OTP allowance, disrupting legitimate two-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, leading to denial of service for legitimate users by exhausting the OTP quota. There is no direct confidentiality or integrity impact reported, but availability of the second-factor authentication mechanism is affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided in the available data. Until a fix is available, restrict access to the plugin's OTP sending functionality to trusted users only, if possible.
