CVE-2025-14354 in Resource Library for Logged In Users Plugin
Summary
by MITRE • 12/12/2025
The Resource Library for Logged In Users plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing nonce validation on multiple administrative functions. This makes it possible for unauthenticated attackers to perform various unauthorized actions including creating, editing, and deleting resources and categories via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The CVE-2025-14354 vulnerability affects the Resource Library for Logged In Users plugin for WordPress, representing a critical cross-site request forgery weakness that has persisted across all versions up to and including 1.4. This vulnerability stems from the absence of proper nonce validation mechanisms within the plugin's administrative functions, creating a fundamental security gap that undermines the integrity of WordPress site management operations. The flaw specifically targets the plugin's resource and category management capabilities, exposing administrators to potential unauthorized modifications of critical content.
The technical implementation of this vulnerability involves the plugin's failure to validate cryptographic nonces during administrative operations, which are essential security tokens designed to prevent unauthorized requests from being executed on behalf of authenticated users. Without these validation checks, malicious actors can construct forged HTTP requests that appear legitimate to the WordPress system, as they lack the necessary security token verification. This weakness operates at the core of WordPress's security architecture, where nonces serve as the primary defense mechanism against CSRF attacks by ensuring that requests originate from legitimate administrative sessions.
The operational impact of this vulnerability extends beyond simple data manipulation, as it allows attackers to perform comprehensive administrative actions without authentication. An attacker can leverage this weakness to create new resources, modify existing content, delete critical categories, and potentially disrupt the entire resource library functionality. The attack vector requires social engineering to trick administrators into clicking malicious links, but once successful, the consequences can be severe as the attacker gains the ability to completely alter the plugin's content structure and potentially compromise the broader site integrity.
This vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in software applications. The implementation flaw directly violates the principle of least privilege and proper authentication verification, creating an attack surface that allows unauthorized modifications to administrative functions. From an ATT&CK framework perspective, this vulnerability maps to T1078 Valid Accounts and T1566 Phishing techniques, as it relies on tricking legitimate users into executing malicious requests while exploiting the trust relationship between the administrator and the WordPress system. The affected plugin's administrative interface becomes a critical entry point for attackers seeking to establish persistent control over resource management functions.
Mitigation strategies should prioritize immediate plugin updates to versions that implement proper nonce validation, as this represents the most direct solution to the vulnerability. Administrators should also implement additional security measures including role-based access controls, regular security audits, and monitoring for suspicious administrative activities. Network-level protections such as web application firewalls can help detect and block malicious requests, while user education regarding phishing awareness remains crucial in preventing successful social engineering attacks. The vulnerability underscores the importance of proper security implementation in WordPress plugins and the necessity of thorough security testing before deployment in production environments.
