Source: CVE Database V5
Vendor/Project: mdesignfa
Product: Namasha By Mdesign

Description

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.

Technical Analysis

CVE-2025-6537 is a Stored Cross-Site Scripting (XSS) vulnerability identified in the Namasha By Mdesign WordPress plugin, affecting all versions up to and including 1.2.00. The vulnerability arises due to improper neutralization of input during web page generation, specifically related to the 'playicon_title' parameter. This parameter lacks sufficient input sanitization and output escaping, allowing authenticated users with Contributor-level access or higher to inject arbitrary JavaScript code into pages. When other users visit these compromised pages, the injected scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or other malicious activities. The vulnerability has a CVSS 3.1 base score of 6.4, categorized as medium severity, with an attack vector of network (remote exploitation), low attack complexity, requiring privileges (Contributor or higher), no user interaction, and a scope change indicating that the vulnerability affects components beyond the initially vulnerable component. Although no known exploits are currently reported in the wild, the vulnerability's nature makes it a significant concern for WordPress sites using this plugin, especially given the widespread use of WordPress in Europe. The vulnerability does not affect unauthenticated users directly but leverages the permissions of authenticated contributors, making internal threat actors or compromised accounts a key risk vector. The absence of patches at the time of reporting further increases exposure risk.

Potential Impact

For European organizations, this vulnerability poses a risk primarily to websites and web applications built on WordPress that utilize the Namasha By Mdesign plugin. The impact includes potential compromise of user sessions, theft of sensitive information, defacement of websites, and distribution of malicious scripts to site visitors. This can lead to reputational damage, loss of customer trust, and potential regulatory non-compliance under GDPR if personal data is exposed or mishandled. Organizations with Contributor-level or higher user roles are at risk of internal misuse or exploitation if accounts are compromised. The scope change in the CVSS vector indicates that the vulnerability could affect multiple components or data flows, potentially allowing attackers to escalate privileges or pivot within the application. Given the popularity of WordPress in Europe, especially among small and medium enterprises, media outlets, and public sector websites, the vulnerability could be leveraged to target these sectors. Additionally, the lack of user interaction required for exploitation means that once a malicious script is injected, any visitor to the affected page may be impacted, increasing the potential reach of an attack.

Mitigation Recommendations

1. Immediate mitigation should include restricting Contributor-level access to trusted users only and reviewing existing user roles to minimize unnecessary privileges. 2. Implement strict input validation and output encoding for the 'playicon_title' parameter within the plugin code; if custom development resources are available, patch the plugin by sanitizing inputs and escaping outputs properly. 3. Monitor WordPress installations for unusual script injections or unexpected changes in page content, using web application firewalls (WAFs) with rules targeting XSS payloads specific to this plugin. 4. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected sites. 5. Regularly audit installed plugins and promptly apply updates once the vendor releases a patch. 6. Consider temporarily disabling or replacing the Namasha By Mdesign plugin with alternative solutions until a secure version is available. 7. Educate site administrators and contributors about the risks of XSS and the importance of secure content management practices. 8. Use security plugins that can detect and block stored XSS attempts in WordPress environments.
