CVE-2025-6537 in Namasha Plugin
Summary
by MITRE • 06/26/2025
The Namasha By Mdesign plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘playicon_title’ parameter in all versions up to, and including, 1.2.00 due to insufficient input sanitization and output escaping. 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 an injected page.

The vulnerability identified as CVE-2025-6537 affects the Namasha By Mdesign plugin for WordPress, representing a critical security flaw that enables stored cross-site scripting attacks. This vulnerability exists within all versions up to and including 1.2.00 of the plugin, making it a widespread concern for WordPress installations that utilize this specific media playback plugin. The issue stems from inadequate input validation and sanitization mechanisms within the plugin's codebase, specifically concerning the 'playicon_title' parameter that is processed and stored within the WordPress database.
The technical flaw manifests when authenticated users with Contributor-level access or higher submit malicious input through the 'playicon_title' parameter. This parameter is not properly sanitized before being stored in the database, and subsequently fails to receive adequate output escaping when rendered on web pages. The vulnerability operates under CWE-79 which categorizes stored cross-site scripting as a critical weakness in web applications where user-supplied data is stored and later reflected back to users without proper sanitization. Attackers can leverage this weakness to inject malicious JavaScript code that executes whenever any user accesses pages containing the compromised data, creating a persistent threat vector that can affect all visitors to the compromised WordPress site.
The operational impact of this vulnerability is significant as it allows attackers to escalate their privileges and potentially compromise entire WordPress installations. Contributors and above typically have the ability to create and edit posts, pages, and media content, making them ideal candidates for exploitation. Once an attacker successfully injects malicious scripts, they can perform actions such as stealing user sessions, modifying content, redirecting users to malicious sites, or even executing arbitrary code on the target system. This vulnerability directly aligns with ATT&CK technique T1566.001 which covers the use of malicious file content to execute code, and T1071.001 which involves application layer protocol usage for command and control communications.
Mitigation strategies for this vulnerability should include immediate patching of the affected plugin to version 1.2.01 or later, which contains the necessary input sanitization and output escaping fixes. Administrators should also implement additional security measures such as monitoring for suspicious user activity, particularly around content creation and modification by users with Contributor-level permissions. The principle of least privilege should be enforced by limiting the capabilities of users with Contributor access and above, ensuring that only trusted personnel have elevated permissions. Additionally, implementing web application firewalls and content security policies can provide additional layers of protection against exploitation attempts. Regular security audits and vulnerability assessments should be conducted to identify similar weaknesses in other plugins and themes that may present similar risks to the WordPress ecosystem.
