What is CVE-2026-16035?

The miniOrange 2FA WordPress plugin, prior to version 6.2.7, contains a vulnerability that allows low-privileged users to send one-time passcode (OTP) emails to any arbitrary recipient. This oversight does not enforce restrictions on who may trigger the OTP configuration process, nor does it bind the OTP recipient to the enrolling user's address. Consequently, this can lead to an exhaustion of the site's metered OTP allowance, hindering legitimate users from receiving their essential second-factor authentication codes.

Affected Version(s)

miniOrange 2FA 0 < 6.2.7

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
