CVE-2025-9206 in Meks Easy Maps Plugin
Summary
by MITRE • 10/03/2025
The Meks Easy Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the post title field in all version up to, and including, 2.1.4. This is due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the map containing the malicious post.

The Meks Easy Maps plugin for WordPress presents a critical stored cross-site scripting vulnerability that affects all versions up to and including 2.1.4. This security flaw resides in the plugin's handling of user-supplied data within the post title field, creating a persistent vector for malicious code execution. The vulnerability stems from inadequate input sanitization and insufficient output escaping mechanisms that fail to properly validate or encode user-provided content before it is stored in the database and subsequently rendered on web pages.
The technical implementation of this vulnerability allows authenticated attackers who possess contributor-level access or higher to inject malicious scripts into the plugin's map display functionality. When a victim accesses a page containing the compromised map, the stored malicious code executes within their browser context, potentially enabling attackers to perform actions on behalf of the victim. This stored XSS vulnerability operates by bypassing standard security controls that would normally prevent script injection, as the malicious content is saved to the database and retrieved during page rendering rather than being processed through a single request-response cycle.
From an operational perspective, this vulnerability poses significant risks to WordPress installations using the Meks Easy Maps plugin. Attackers with contributor privileges can leverage this flaw to execute persistent malicious scripts that may steal session cookies, redirect users to phishing sites, or perform unauthorized actions within the WordPress admin interface. The impact extends beyond simple script execution as the vulnerability can be exploited to establish persistent backdoors or facilitate more sophisticated attacks such as privilege escalation within the WordPress environment. The fact that this vulnerability affects authenticated users with relatively low privileges makes it particularly concerning as it can be exploited by insiders or compromised accounts with contributor-level access.
The vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and demonstrates poor input validation practices that violate secure coding principles. From an ATT&CK framework perspective, this vulnerability maps to techniques involving client-side code injection and can be leveraged for privilege escalation and persistence within the WordPress environment. Organizations should implement immediate mitigations including updating to the latest plugin version, implementing proper input validation and output escaping mechanisms, and restricting contributor-level privileges where possible. Additionally, regular security audits of WordPress plugins and enforcement of strict access controls can help prevent exploitation of similar vulnerabilities in the future, as the stored nature of this XSS attack means that once a malicious script is injected, it will continue to execute until manually removed or the plugin is updated to address the vulnerability.
