At a glance

CVE-2025-12884 is a medium-severity Improper Access Control vulnerability in the Advanced Ads – Ad Manager & AdSense WordPress plugin, affecting versions <= 2.0.14. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.0.15; sites on affected versions should update now. Disclosed February 2026, reported by Supakiad S. (m3ez) (m3ez).

Vulnerability Overview

The Advanced Ads – Ad Manager & AdSense plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 2.0.14. This is due to the plugin not properly verifying that a user is authorized to perform an action in the `placement_update_item()` function. This makes it possible for authenticated attackers, with subscriber-level access and above, to update ad placements, allowing them to change which ad or ad group a placement serves.

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-284: Improper Access Control

Advanced Ads – Ad Manager & AdSense <= 2.0.14 carries this weakness at placement_update_item(), and reaching it takes an account at Subscriber level or above. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Advanced Ads – Ad Manager & AdSense the fix is 2.0.15: builds <= 2.0.14 are affected, anything from 2.0.15 onward is not.

Remediation

Update to version 2.0.15, 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: Advanced Ads – Ad Manager & AdSense 2.0.15 closes this, and updating the plugin is the step that ends it.
