At a glance
CVE-2026-77770 is a high-severity Missing Authentication for Critical Function vulnerability in the miniOrange 2FA WordPress plugin, affecting versions 5.3.24 – 19.2 · 2 branches. It carries a CVSS score of 7.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 19.3; sites on affected versions should update now. Disclosed September 2026, reported by Osman Hussein.
Vulnerability Overview
The miniOrange 2FA – Two Factor Authentication for WordPress (OTP, SMS, Email, Google Authenticator) plugin for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check in versions 5.3.24 to 6.3.0. This makes it possible for unauthenticated attackers to delete arbitrary option values on the WordPress site. This can be leveraged to delete an option that would create an error on the site and deny service to legitimate users.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-306: Missing Authentication for Critical Function
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
Remediation
Update to one of the following versions, or a newer patched version: 19.3, 6.3.1
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: miniOrange 2FA 19.3 closes this, and updating the plugin is the step that ends it.
