At a glance

CVE-2026-1729 is a critical-severity Missing Authentication for Critical Function vulnerability in the AdForest WordPress theme, affecting versions <= 6.0.12. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 6.0.13; sites on affected versions should update now. Disclosed February 2026, reported by Phat RiO.

Vulnerability Overview

The AdForest theme for WordPress is vulnerable to authentication bypass in all versions up to, and including, 6.0.12. This is due to the plugin not properly verifying a user's identity prior to authenticating them through the 'sb_login_user_with_otp_fun' function. This makes it possible for unauthenticated attackers to log in as arbitrary users, including administrators.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

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 version 6.0.13, or a newer patched version

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. None of that substitutes for the fix: AdForest 6.0.13 closes this, and updating the theme is the step that ends it.
