CVE-2025-62121 is a Stored Cross-Site Scripting (XSS) vulnerability categorized under CWE-79, affecting the Imran Emu suite of web plugins: Logo Slider, Logo Carousel, Logo Showcase, and Client Logo, up to version 1.8.1. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be stored on the server and executed in the browsers of users who view the affected pages. The CVSS 3.1 base score is 5.9 (medium), with an attack vector of network (remote), low attack complexity, but requiring high privileges and user interaction. This means an attacker must have authenticated access with elevated privileges to inject the malicious payload, and a victim must interact with the compromised content for the exploit to succeed. The vulnerability impacts confidentiality, integrity, and availability by enabling attackers to steal session tokens, perform actions on behalf of users, or deface content. No patches or known public exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The affected products are commonly used as WordPress plugins or similar CMS add-ons, making websites that utilize these components vulnerable to targeted attacks. The scope of impact includes any web application using these plugins, especially those with multiple users or administrative roles.

For European organizations, this vulnerability can lead to unauthorized access to sensitive user data, session hijacking, and potential defacement or disruption of web services. Organizations relying on the affected Imran Emu plugins for branding or client showcase on their websites may face reputational damage if exploited. The requirement for high privileges to inject the payload means insider threats or compromised administrative accounts pose a significant risk. The vulnerability could also serve as a foothold for further attacks within the network, especially in environments where web applications are integrated with internal systems. Given the widespread use of WordPress and similar CMS platforms in Europe, particularly among SMEs and enterprises in sectors like finance, retail, and public services, the risk is non-trivial. Additionally, GDPR implications arise if personal data is exposed or manipulated through this vulnerability, potentially leading to regulatory penalties.

1. Immediately audit user roles and permissions to ensure only trusted users have high-level access capable of injecting content. 2. Implement strict input validation and output encoding on all user-supplied data, especially in areas where logos or client information are uploaded or managed. 3. Monitor web application logs and user activity for unusual behavior indicative of attempted XSS exploitation. 4. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Isolate or sandbox affected plugins where possible to limit the scope of potential script execution. 6. Stay informed on vendor updates and apply patches promptly once released. 7. Consider temporarily disabling or replacing the affected plugins if immediate patching is not feasible. 8. Conduct regular security assessments and penetration testing focusing on web application vulnerabilities including XSS. 9. Educate administrators and content managers about the risks of injecting untrusted content and safe content management practices.
