CVE-2025-13592 is a remote code execution (RCE) vulnerability classified under CWE-94 (Improper Control of Generation of Code) found in the Advanced Ads – Ad Manager & AdSense plugin for WordPress developed by monetizemore. The vulnerability affects all plugin versions up to and including 2.0.14. It arises from insufficient sanitization and validation of the 'change-ad__content' shortcode parameter, which allows an authenticated attacker with editor-level or higher permissions to inject arbitrary code that the server executes. This flaw enables attackers to execute malicious PHP or other code on the web server hosting the WordPress site, potentially leading to full system compromise. The CVSS v3.1 base score is 7.2, reflecting a high severity due to network attack vector, low attack complexity, required privileges (high), no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits are reported in the wild, the vulnerability poses a significant risk to websites using this plugin, especially those with multiple editors or contributors. The lack of available patches at the time of publication necessitates immediate mitigation steps to reduce exposure.

Successful exploitation of this vulnerability can lead to complete compromise of the affected WordPress server. Attackers could execute arbitrary code, leading to data theft, defacement, malware deployment, or pivoting to other internal systems. The confidentiality of sensitive data stored or processed by the website can be breached, integrity of website content and configurations can be altered, and availability can be disrupted by destructive payloads or denial-of-service conditions. Organizations relying on this plugin for ad management risk reputational damage, financial loss, and regulatory penalties if customer or user data is exposed. Given WordPress's widespread use globally, the impact can be extensive, especially for media, e-commerce, and content-heavy websites that rely on monetizemore's Advanced Ads plugin.

1. Immediately restrict editor-level and higher permissions to trusted users only until a patch is available. 2. Disable or remove the Advanced Ads plugin if it is not critical to operations. 3. Monitor and audit user activity logs for suspicious shortcode usage or unexpected changes in ad content. 4. Implement Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the 'change-ad__content' parameter. 5. Regularly update WordPress core and plugins; apply security patches from monetizemore as soon as they are released. 6. Employ principle of least privilege for WordPress roles to minimize the number of users with editor or higher permissions. 7. Conduct code reviews and vulnerability scans on custom shortcodes or plugin extensions. 8. Backup website data and configurations frequently to enable rapid recovery in case of compromise.
