CVE-2025-23871 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Bas Matthee LSD Google Maps Embedder plugin, a WordPress plugin used to embed Google Maps into websites. The vulnerability affects all versions up to and including 1.1. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform actions without the user's consent. In this case, the plugin does not properly validate the origin or authenticity of requests that perform sensitive actions, allowing attackers to craft malicious web pages that, when visited by authenticated users, trigger unintended plugin operations. Although no known exploits are currently reported in the wild, the vulnerability poses a risk to the integrity of the affected websites, potentially allowing attackers to manipulate map embeds or related settings. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed, but the technical details confirm the issue is recognized and published by Patchstack. The vulnerability requires the victim to be authenticated on the target site, and no user interaction beyond visiting a malicious page is necessary. This flaw could be leveraged in targeted attacks against websites using this plugin, especially those with high-value or sensitive content.

The primary impact of this CSRF vulnerability is on the integrity of affected websites using the LSD Google Maps Embedder plugin. Attackers can cause authenticated users to unknowingly perform unauthorized actions, potentially altering map configurations or embedding malicious content. This can lead to misinformation, defacement, or disruption of user experience. While the vulnerability does not directly lead to remote code execution or data exfiltration, it can be used as a stepping stone in multi-stage attacks or combined with other vulnerabilities to escalate impact. Organizations relying on this plugin for critical location-based services or customer-facing content may experience reputational damage and loss of user trust. The requirement for user authentication limits the scope but does not eliminate risk, especially for sites with many authenticated users or administrators. Since no patches are currently linked, organizations remain exposed until mitigations are applied. The lack of known exploits in the wild reduces immediate risk but does not preclude future exploitation.

Organizations should monitor for official patches or updates from the Bas Matthee project and apply them promptly once available. In the interim, implement strict anti-CSRF protections such as verifying CSRF tokens on all state-changing requests within the plugin. Review and harden cookie attributes by setting SameSite flags to 'Strict' or 'Lax' to reduce cross-origin request risks. Limit the number of users with administrative privileges to reduce the attack surface. Employ Content Security Policy (CSP) headers to restrict the domains that can execute scripts or submit forms on behalf of the site. Conduct regular security audits of WordPress plugins and remove or replace those that are unmaintained or vulnerable. Educate users and administrators about the risks of visiting untrusted websites while authenticated to sensitive systems. Finally, consider implementing web application firewalls (WAFs) with rules to detect and block suspicious CSRF attempts targeting the plugin endpoints.
