CVE-2025-14907 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Moderate Selected Posts plugin for WordPress, versions up to and including 1.4. The root cause is the absence of nonce verification in the msp_admin_page() function, which is responsible for handling administrative plugin settings. Nonce tokens are security mechanisms used in WordPress to ensure that requests to change state originate from legitimate users and not from malicious third-party sites. Without this verification, an attacker can craft a malicious link or webpage that, when visited by a logged-in WordPress administrator, causes unintended changes to the plugin’s configuration. This attack vector requires no authentication by the attacker but does require that the administrator performs an action such as clicking a link or visiting a malicious site. The vulnerability affects the integrity of the plugin’s settings but does not expose confidential data or disrupt service availability. The CVSS 3.1 base score of 4.3 reflects the network attack vector, low complexity, no privileges required, but user interaction is necessary. No known exploits have been reported in the wild, and no official patches or updates have been linked yet. The vulnerability was reserved in December 2025 and published in January 2026 by Wordfence, indicating recent discovery and disclosure.

The primary impact of this vulnerability is the potential unauthorized modification of plugin settings by an attacker leveraging CSRF. This can lead to altered plugin behavior, which may degrade site functionality, weaken security controls, or enable further exploitation depending on the plugin’s role. Since the attacker cannot directly steal data or cause denial of service, the confidentiality and availability impacts are minimal. However, integrity compromise of plugin settings can indirectly affect site security posture and trustworthiness. Organizations running WordPress sites with this plugin installed are at risk if administrators are tricked into interacting with malicious content. This risk is amplified in environments where administrators have high privileges and where the plugin controls critical site features. The lack of authentication requirement for the attacker and the ease of exploitation via social engineering increase the threat surface. While no active exploitation is known, the vulnerability could be targeted in phishing campaigns or malicious advertising to gain foothold or escalate privileges on affected sites.

To mitigate this vulnerability, organizations should first verify if they are using the Moderate Selected Posts plugin version 1.4 or earlier and upgrade to a patched version once available. In the absence of an official patch, site administrators or developers should implement nonce verification in the msp_admin_page() function to ensure all state-changing requests include a valid nonce token. This can be done by adding WordPress’s built-in nonce functions such as wp_nonce_field() in forms and verifying with check_admin_referer() on request handling. Additionally, administrators should be trained to avoid clicking suspicious links and to verify URLs before interacting with administrative interfaces. Employing web application firewalls (WAFs) that can detect and block CSRF attempts may provide temporary protection. Regularly auditing plugin configurations and monitoring for unexpected changes can help detect exploitation attempts early. Finally, limiting administrative access and enforcing multi-factor authentication reduces the risk of successful exploitation.
