Disclosed October 2026, reported by Ananda Dhakal.
Vulnerability Overview
The WP Synchro – The Ultimate WordPress Migration Tool plugin for WordPress is vulnerable to 2-Factor Authentication Bypass in all versions up to, and including, 1.16.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to bypass 2fa when logging in.
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 interaction from a victim user.
CWE-287: Improper Authentication
Reaching this weakness in WP Synchro <= 1.16.1 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.
An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. No fixed build of this plugin is recorded for WP Synchro yet, so installs running <= 1.16.1 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
