WordPress · Cm Ad Changer · CVE-2026-9236
**Name of the Vulnerable Software and Affected Versions**
CM Ad Changer versions prior to 2.0.8
**Description**
The CM Ad Changer plugin for WordPress is susceptible to Cross-Site Request Forgery (CSRF), a flaw where an attacker tricks a victim into executing unwanted actions. This occurs due to missing or incorrect nonce validation within the `cmac campaigns action()` function. Unauthenticated attackers can exploit this to permanently delete arbitrary advertising campaigns, including associated banner records and uploaded files, by inducing a site administrator to click a malicious link.
**Recommendations**
Update the plugin to version 2.0.8 or later.
As a temporary workaround, restrict administrative access to the plugin settings to minimize the risk of exploitation.
