At a glance

CVE-2025-8359 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the AdForest WordPress theme, affecting versions <= 6.0.9. 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 6.0.10; sites on affected versions should update now. Disclosed September 2025, reported by Tonn.

Vulnerability Overview

The AdForest theme for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 6.0.9. This is due to the plugin not properly verifying a user's identity prior to authenticating them. This makes it possible for unauthenticated attackers to log in as other users, including administrators, without access to a password.

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-288: Authentication Bypass Using an Alternate Path or Channel

Reaching this weakness in AdForest <= 6.0.9 takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For AdForest the fix is 6.0.10: builds <= 6.0.9 are affected, anything from 6.0.10 onward is not.

Remediation

Update to version 6.0.10, 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 6.0.10 closes this, and updating the theme is the step that ends it.
