CVE-2025-48259 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'WP Mapa Politico España' developed by Juan Carlos. This vulnerability affects versions up to and including 3.8.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unwanted actions on behalf of the user without their consent. In this case, the WP Mapa Politico España plugin lacks adequate CSRF protections, allowing attackers to craft malicious requests that, when executed by an authenticated administrator or user with sufficient privileges, could alter plugin settings or perform other unauthorized actions. The CVSS v3.1 base score is 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires no privileges, but does require user interaction (such as clicking a link). The impact is limited to integrity, with no confidentiality or availability impact. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-352, which specifically relates to CSRF issues. Since this plugin is focused on political maps of Spain, it is likely used primarily by Spanish organizations or entities with interest in Spanish political data visualization within WordPress environments.

For European organizations, particularly those in Spain or with Spanish political content, this vulnerability poses a risk of unauthorized modification of political map data or plugin configurations. Such unauthorized changes could misrepresent political information, potentially influencing public perception or internal decision-making processes. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could undermine trust in the affected websites. Organizations using this plugin in governmental, educational, or media sectors may face reputational damage or misinformation risks. Since exploitation requires user interaction and no privileges, attackers could target users with editing rights via phishing or social engineering to trigger malicious requests. The impact is more pronounced in environments where the plugin is actively used to display politically sensitive or public-facing information.

Organizations should immediately audit their WordPress installations for the presence of the WP Mapa Politico España plugin and verify the version in use. Until an official patch is released, administrators should consider disabling or removing the plugin if it is not critical. For sites requiring the plugin, implement additional CSRF protections at the web application firewall (WAF) level by blocking suspicious cross-site requests or enforcing strict referrer and origin header checks. Educate users with administrative or editing privileges about the risks of clicking unknown links or visiting untrusted websites while logged into WordPress. Monitor web server logs for unusual POST requests to the plugin endpoints. Once a patch becomes available, prioritize its deployment. Additionally, consider implementing Content Security Policy (CSP) headers to reduce the risk of malicious script execution that could facilitate CSRF attacks.
