CVE-2025-14354 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the 'Resource Library for Logged In Users' WordPress plugin developed by doubledome, affecting all versions up to and including 1.4. The vulnerability stems from the absence of nonce validation on several administrative functions within the plugin. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and not from malicious third-party sites. Without nonce validation, an attacker can craft a malicious request that, when executed by an authenticated administrator (e.g., by clicking a link), performs unauthorized actions such as creating, editing, or deleting resources and categories within the plugin. This type of attack compromises the integrity of the website content managed by the plugin but does not directly affect confidentiality or availability. The attack vector is remote and requires no prior authentication by the attacker, but it does require user interaction from an administrator. The vulnerability was published on December 12, 2025, with a CVSS v3.1 base score of 4.3, indicating a medium severity level. No public exploits have been reported to date. The lack of nonce validation is a common security oversight in WordPress plugin development, and this vulnerability highlights the importance of implementing standard security controls to prevent CSRF attacks. Organizations using this plugin should monitor for updates or patches from the vendor and consider interim mitigations to protect administrative interfaces.

For European organizations, this vulnerability can lead to unauthorized modification or deletion of resources and categories managed by the affected WordPress plugin, potentially disrupting content management workflows and damaging data integrity. While the vulnerability does not directly expose sensitive data or cause denial of service, unauthorized content changes can undermine trust, cause operational disruptions, and may be leveraged as part of broader attack chains, such as defacement or phishing campaigns. Organizations with public-facing WordPress sites that rely on this plugin for resource management are particularly at risk. The requirement for administrator interaction means that social engineering or phishing campaigns targeting site administrators could facilitate exploitation. Given the widespread use of WordPress across Europe, especially in sectors like education, government, and SMEs, the vulnerability could impact a broad range of organizations. The medium severity rating suggests moderate risk, but the potential for integrity compromise warrants prompt attention.

1. Monitor for and apply official patches or updates from the plugin vendor as soon as they become available. 2. In the absence of patches, implement manual nonce validation on all administrative functions within the plugin by modifying the plugin code or using security plugins that enforce nonce checks. 3. Restrict administrative access to trusted networks or VPNs to reduce exposure to CSRF attacks. 4. Educate WordPress administrators about the risks of clicking unsolicited links, especially those received via email or messaging platforms. 5. Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting WordPress administrative endpoints. 6. Regularly audit and monitor logs for suspicious administrative actions that could indicate exploitation attempts. 7. Consider disabling or replacing the plugin if timely patches are not forthcoming and the plugin is critical to operations.
