CVE-2024-31269: Easy Google Maps CSRF Vulnerability

CVE-2024-31269 Overview

CVE-2024-31269 is a Cross-Site Request Forgery (CSRF) vulnerability in the Supsystic Easy Google Maps plugin for WordPress. The flaw affects all versions from initial release through 1.11.11. An attacker can craft a malicious request that, when triggered by an authenticated administrator visiting an attacker-controlled page, executes privileged actions on the WordPress site. The weakness is classified under CWE-352. User interaction is required, but exploitation requires no prior authentication on the attacker side, and the network attack surface is broad.

Critical Impact
Successful exploitation enables unauthorized state-changing actions in the plugin with the privileges of the targeted administrator, leading to high impact on confidentiality, integrity, and availability.

Affected Products

Supsystic Easy Google Maps plugin for WordPress
All versions up to and including 1.11.11
WordPress installations with the plugin active

Technical Details for CVE-2024-31269

Vulnerability Analysis

The Easy Google Maps plugin exposes administrative actions that lack proper anti-CSRF protection. Sensitive endpoints fail to validate a unique, unpredictable token tied to the authenticated session. As a result, the server cannot distinguish between requests intentionally issued by a logged-in administrator and forged requests originating from third-party origins.

The attack proceeds through the victim's browser. When an authenticated administrator visits a page controlled by the attacker, the browser automatically attaches the WordPress session cookies to the forged request. The plugin processes the request as legitimate and performs the requested operation, modifying plugin state or settings.

The Exploit Prediction Scoring System (EPSS) reports a probability of 0.227% with a percentile of 13.374, indicating low observed exploitation activity. No public proof-of-concept or in-the-wild exploitation has been recorded.

Root Cause

The root cause is the absence or improper validation of WordPress nonces (wp_nonce) on state-changing administrative requests. Without a per-session, per-action token verified server-side, the plugin trusts any request that carries valid authentication cookies. This is a classic violation of CWE-352.

Attack Vector

An attacker hosts a malicious page or injects markup into a third-party site visited by a WordPress administrator. The page contains an auto-submitting HTML form or image tag pointing at the vulnerable plugin endpoint. When the administrator loads the page, the browser issues the forged request with valid session cookies, and the plugin executes the embedded action. See the Patchstack Vulnerability Report for additional context.

Detection Methods for CVE-2024-31269

Indicators of Compromise

Unexpected modifications to Easy Google Maps plugin configuration or map entries.
WordPress administrator activity logs showing POST requests to plugin endpoints with Referer headers pointing to unknown external origins.
Plugin actions executed immediately after an administrator visited an external link.

Detection Strategies

Inspect web server access logs for requests to Easy Google Maps endpoints missing or carrying invalid _wpnonce parameters.
Correlate administrator browsing telemetry with subsequent privileged plugin actions to identify CSRF chains.
Monitor referer headers on administrative requests for cross-origin patterns.

Monitoring Recommendations

Enable WordPress audit logging plugins to capture all plugin setting changes with user, IP, and referer metadata.
Forward web server and WordPress audit logs to a centralized SIEM for cross-source correlation.
Alert on administrator sessions issuing plugin configuration changes shortly after navigation to external domains.

How to Mitigate CVE-2024-31269

Immediate Actions Required

Update Easy Google Maps to a version later than 1.11.11 once the vendor publishes a patched release.
If no fixed version is available, deactivate and remove the plugin from production WordPress sites.
Force re-authentication of administrators and rotate session secrets after confirming exposure.

Patch Information

No vendor advisory URL is published in the NVD record. Refer to the Patchstack Vulnerability Report for the latest fix status and version guidance. Administrators should monitor the plugin's WordPress.org page for an updated release that adds nonce validation to all state-changing endpoints.

Workarounds

Restrict WordPress administrative access to trusted networks using IP allowlists or VPN.
Deploy a web application firewall rule that blocks POST requests to plugin endpoints lacking a valid _wpnonce token.
Train administrators to use a dedicated browser profile for WordPress administration and to avoid following untrusted links while authenticated.

bash

# Example WAF rule (ModSecurity) blocking cross-origin POSTs to the plugin
SecRule REQUEST_METHOD "@streq POST" \
  "chain,id:1003101,phase:2,deny,status:403,msg:'Block CSRF on Easy Google Maps'"
  SecRule REQUEST_URI "@contains /wp-admin/admin.php?page=supsystic-gmp" \
    "chain"
    SecRule &ARGS:_wpnonce "@eq 0"
