CVE-2025-48259: WP Mapa Politico España CSRF Vulnerability

CVE-2025-48259 Overview

CVE-2025-48259 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the WP Mapa Politico España WordPress plugin by Juan Carlos. The flaw impacts all plugin versions up to and including 3.8.0. An attacker can craft a malicious request that, when triggered by an authenticated administrator visiting an attacker-controlled page, causes unauthorized changes to plugin settings.

The vulnerability is categorized under CWE-352 (Cross-Site Request Forgery) and requires user interaction to succeed. No public exploit is currently available, and the issue is not listed in the CISA Known Exploited Vulnerabilities catalog.

Critical Impact
Successful exploitation allows attackers to modify plugin settings in the context of an authenticated administrator, undermining the integrity of the affected WordPress site's configuration.

Affected Products

WP Mapa Politico España plugin versions up to and including 3.8.0
WordPress installations with the vulnerable plugin activated
Administrator sessions authenticated to WordPress at the time of exploitation

Technical Details for CVE-2025-48259

Vulnerability Analysis

The vulnerability stems from missing or improperly validated anti-CSRF tokens on state-changing requests within the WP Mapa Politico España plugin. Administrative actions such as settings updates do not verify request origin, allowing forged requests submitted from external contexts to be processed as legitimate.

Exploitation requires the attacker to trick an authenticated administrator into visiting a malicious page or clicking a crafted link. Once triggered, the browser submits an authenticated request to the vulnerable endpoint, applying attacker-chosen settings.

The attack is network-accessible with low complexity and requires no privileges from the attacker. It does impact integrity, but confidentiality and availability are not directly affected.

Root Cause

The root cause is the absence of proper CSRF protection on settings-management endpoints. WordPress provides wp_nonce_field() and check_admin_referer() primitives, but the plugin fails to enforce nonce validation for its administrative operations up through version 3.8.0.

Attack Vector

An attacker hosts a webpage containing an auto-submitting form or image tag that targets the plugin's administrative endpoint. When a logged-in WordPress administrator loads this page, their browser transmits authenticated cookies alongside the forged request. The plugin processes the request without verifying its origin, allowing settings modification.

Detection Methods for CVE-2025-48259

Indicators of Compromise

Unexpected changes to WP Mapa Politico España plugin settings in the WordPress admin interface
HTTP POST requests to plugin admin endpoints with Referer headers pointing to external, untrusted domains
Administrator session activity coinciding with visits to unfamiliar external sites

Detection Strategies

Review WordPress audit logs for plugin settings modifications that do not correlate with legitimate administrator activity
Monitor web server access logs for requests to plugin admin endpoints lacking valid _wpnonce parameters
Correlate administrator browsing telemetry with subsequent plugin configuration changes to identify forced-request patterns

Monitoring Recommendations

Enable a WordPress activity logging plugin to capture settings changes with user, IP, and timestamp metadata
Deploy a Web Application Firewall (WAF) with rules that inspect Referer and Origin headers on WordPress admin POST requests
Alert on administrator accounts performing settings changes outside expected maintenance windows

How to Mitigate CVE-2025-48259

Immediate Actions Required

Update the WP Mapa Politico España plugin to a version newer than 3.8.0 once a patched release becomes available from the vendor
Temporarily deactivate the plugin if a patched version is not yet available and the functionality is not business-critical
Instruct administrators to log out of WordPress before browsing untrusted sites and to use separate browser profiles for admin work

Patch Information

At the time of publication, the vulnerability affects all versions through 3.8.0. Consult the Patchstack Vulnerability Report for the latest fixed-version information and vendor advisories.

Workarounds

Restrict access to /wp-admin/ via IP allowlisting at the web server or WAF layer to reduce exposure of authenticated sessions
Enforce short WordPress session lifetimes and require re-authentication for sensitive administrative operations
Deploy browser-side protections such as SameSite=Strict cookies for the WordPress session and disable third-party cookies for admin users

bash

# Example nginx configuration to restrict wp-admin access by IP
location ^~ /wp-admin/ {
    allow 203.0.113.0/24;
    deny all;
    try_files $uri $uri/ /index.php?$args;
}
