CVE-2025-14907 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Moderate Selected Posts plugin for WordPress, developed by hallsofmontezuma. This vulnerability exists in all plugin versions up to and including 1.4 due to the absence of nonce verification in the msp_admin_page() function, which is responsible for handling administrative plugin settings. Nonce verification is a security mechanism used to ensure that requests to change state are intentional and originate from legitimate users. Without this protection, attackers can craft malicious URLs or web pages that, when visited by an authenticated WordPress administrator, cause unintended changes to the plugin’s configuration. The attack vector requires no prior authentication (AV:N) and has low attack complexity (AC:L), but does require user interaction (UI:R), specifically the administrator clicking a malicious link. The vulnerability does not compromise confidentiality or availability but can affect the integrity of the plugin settings, potentially leading to misconfigurations that could be leveraged for further attacks or disruptions. The CVSS v3.1 base score is 4.3, categorized as medium severity. No patches or known exploits are currently reported, but the risk remains significant due to the widespread use of WordPress and the potential for social engineering to facilitate exploitation.

For European organizations, this vulnerability poses a risk primarily to the integrity of WordPress sites using the Moderate Selected Posts plugin. Unauthorized changes to plugin settings could lead to altered website behavior, potential exposure to additional vulnerabilities, or disruption of site functionality. While it does not directly compromise sensitive data or site availability, the integrity impact can be a stepping stone for attackers to escalate privileges or implant malicious content. Organizations relying on WordPress for public-facing websites, intranets, or content management should be vigilant. The risk is heightened in sectors with high-value targets such as government, finance, and media, where website integrity is critical. Additionally, the need for administrator interaction means that targeted phishing or social engineering campaigns could facilitate exploitation, increasing the threat to organizations with less mature security awareness programs.

1. Monitor for and apply official patches or updates from the plugin vendor as soon as they become available. 2. Until patches are released, restrict administrative access to trusted personnel only and enforce multi-factor authentication (MFA) for all WordPress admin accounts to reduce the risk of compromised credentials. 3. Educate WordPress administrators about the risks of phishing and social engineering attacks, emphasizing caution when clicking on unexpected links or emails. 4. Implement Content Security Policy (CSP) headers and SameSite cookie attributes to reduce the risk of CSRF exploitation. 5. Use security plugins that can detect and block suspicious requests or unauthorized changes to plugin settings. 6. Regularly audit WordPress plugin configurations and logs for unauthorized changes or anomalies. 7. Consider temporarily disabling or replacing the Moderate Selected Posts plugin if it is not critical to operations until a secure version is available.
