CVE-2025-58687 is a high-severity vulnerability identified in the WP CMS Ninja Current Age Plugin, a WordPress plugin used to display current age information on websites. The vulnerability is classified as a Cross-Site Request Forgery (CSRF) issue (CWE-352) that enables an attacker to perform unauthorized actions on behalf of an authenticated user. Specifically, this CSRF flaw allows an attacker to inject stored Cross-Site Scripting (XSS) payloads into the plugin’s data, which are then persistently stored and executed when viewed by users or administrators. The vulnerability affects all versions of the Current Age Plugin up to and including version 1.6. The CVSS 3.1 base score is 7.1, indicating a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact metrics indicate low confidentiality, integrity, and availability impacts individually, but combined they can lead to significant compromise. The absence of available patches at the time of publication increases the risk. Although no known exploits are currently in the wild, the vulnerability’s nature and ease of exploitation make it a credible threat. The CSRF vulnerability allows attackers to trick authenticated users into submitting malicious requests that inject persistent XSS scripts, potentially leading to session hijacking, privilege escalation, or further exploitation within the WordPress environment.

For European organizations using WordPress websites with the WP CMS Ninja Current Age Plugin, this vulnerability poses a significant risk. The stored XSS resulting from the CSRF attack can lead to unauthorized actions such as account takeover, data theft, or defacement of websites. This is particularly critical for organizations handling sensitive user data or providing services that rely on trust and data integrity. The exploitation could compromise the confidentiality of user information, integrity of website content, and availability if attackers disrupt normal operations. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network, potentially affecting backend systems. Given the widespread use of WordPress in Europe across sectors including government, education, and commerce, the vulnerability could have broad implications. The requirement for user interaction (e.g., clicking a malicious link) means phishing campaigns could be an effective attack vector, increasing the threat surface. The lack of patches at the time of disclosure means organizations must rely on mitigation strategies to reduce risk until updates are available.

European organizations should implement several targeted mitigation strategies: 1) Immediately audit WordPress sites to identify installations of the WP CMS Ninja Current Age Plugin and determine the version in use. 2) Temporarily disable or remove the plugin if it is not essential to reduce exposure. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block CSRF and XSS attack patterns targeting the plugin’s endpoints. 4) Enforce strict Content Security Policy (CSP) headers to limit the execution of injected scripts. 5) Educate users and administrators about phishing risks and the importance of not clicking suspicious links, as user interaction is required for exploitation. 6) Monitor logs for unusual POST requests or suspicious activity related to the plugin. 7) Once a patch is released, prioritize timely application of updates. 8) Consider implementing additional CSRF tokens or nonce verification in custom plugin code if feasible. 9) Regularly back up website data to enable recovery in case of compromise. These measures go beyond generic advice by focusing on immediate risk reduction and detection specific to the plugin’s vulnerability characteristics.
