Authorization Bypass Through User-Controlled Key vulnerability in Monetizemore Advanced Ads allows Retrieve Embedded Sensitive Data.
This issue affects Advanced Ads: from n/a through 2.0.26.
CVE-2026-54816 is a high-severity vulnerability in Monetizemore Advanced Ads affecting versions up to and including 2.0.21. It involves improper control of code generation, classified as CWE-94, which allows remote code inclusion. This vulnerability can lead to full compromise of confidentiality, integrity, and availability of the affected system. No official patch or remediation guidance is currently provided by the vendor.
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.
The Advanced Ads – Ad Manager & AdSense plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter in all versions up to, and including, 2.0.15 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Advanced Ads plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.0.14 via the 'change-ad__content' shortcode parameter. This allows authenticated attackers with editor-level permissions or above, to execute code on the server.
The Advanced Ads – Ad Manager & AdSense plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.0.12 via the select_one() function. This is due to the endpoint not properly restricting access to the AJAX endpoint or limiting the functions that can be called to safe functions. This makes it possible for unauthenticated attackers to call arbitrary functions beginning with get_the_ like get_the_excerpt which can make information exposure possible.
The Advanced Ads plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.52.1 via deserialization of untrusted input in the 'placement_slug' parameter. This makes it possible for authenticated attackers to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
The Advanced Ads – Ad Manager & AdSense plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Advanced Ad widget in all versions up to, and including, 1.52.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
