CVE-2025-58672 is a medium severity vulnerability classified under CWE-862 (Missing Authorization) affecting the WordPress plugin WP User Frontend developed by Tareq Hasan. This vulnerability arises from improperly configured access control mechanisms within the plugin, allowing users with limited privileges (PR:L - privileges required: low) to perform unauthorized actions that should be restricted. The CVSS 3.1 base score is 5.4, indicating a moderate risk level. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), and the scope remains unchanged (S:U). Although confidentiality impact is none (C:N), the vulnerability impacts integrity (I:L) and availability (A:L), meaning an attacker can alter data or disrupt service availability without needing elevated privileges or user interaction. The affected versions include all versions up to 4.1.11, with no specific earliest affected version stated. No patches or known exploits in the wild have been reported at the time of publication (September 22, 2025). The vulnerability allows exploitation of incorrectly configured access control security levels, which could enable attackers to bypass authorization checks and perform actions beyond their intended permissions, potentially leading to data manipulation or denial of service within the affected WordPress sites using this plugin.

For European organizations, especially those relying on WordPress for their web presence and using the WP User Frontend plugin, this vulnerability poses a tangible risk. Exploitation could lead to unauthorized modification of frontend user data or disruption of frontend functionalities, impacting business operations, customer interactions, and service availability. Given the widespread use of WordPress in Europe across various sectors including e-commerce, media, and public services, the vulnerability could affect a broad range of organizations. The integrity and availability impacts could result in defacement, data tampering, or temporary denial of service, potentially damaging reputation and causing operational downtime. While no confidentiality breach is indicated, the ability to alter data or disrupt services can still have significant business consequences. The absence of known exploits in the wild suggests a window for proactive mitigation before active attacks emerge.

Organizations should immediately audit their WordPress installations to identify the presence and version of the WP User Frontend plugin. Since no official patch links are currently available, administrators should consider temporarily disabling the plugin or restricting access to its functionalities to trusted users only. Implementing additional access control layers at the web server or application firewall level can help mitigate unauthorized access attempts. Monitoring logs for unusual activity related to the plugin’s endpoints is recommended to detect potential exploitation attempts early. Organizations should subscribe to vendor or security advisories for updates and apply patches promptly once released. Additionally, reviewing and tightening user roles and permissions within WordPress can reduce the risk of privilege misuse. Employing a web application firewall (WAF) with custom rules targeting known exploit patterns for this vulnerability can provide an interim protective measure.
