CVE-2025-47524 is a medium-severity Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the 'karim42 Quran multilanguage Text & Audio' application up to version 2.3.23. The vulnerability arises from improper neutralization of user input during web page generation, allowing malicious scripts to be stored and subsequently executed in the context of other users viewing the affected pages. The CVSS 3.1 base score is 5.9, reflecting a network attack vector with low attack complexity but requiring high privileges and user interaction. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as attackers can execute arbitrary scripts that may steal session tokens, manipulate displayed content, or perform actions on behalf of authenticated users. The scope is changed (S:C), indicating that the vulnerability affects components beyond the initially vulnerable component, potentially impacting the entire application or user base. No known exploits are reported in the wild, and no patches have been linked yet. Stored XSS vulnerabilities are particularly dangerous in web applications with authenticated users, as they can lead to account compromise, data theft, or persistent defacement. Given the religious and cultural significance of the Quran multilanguage Text & Audio application, exploitation could also have reputational and social impacts.

For European organizations, the impact depends on the extent to which this application is used within their environments. Organizations that deploy or integrate the karim42 Quran multilanguage Text & Audio application—such as religious institutions, educational bodies, or cultural organizations—may face risks of user account compromise, unauthorized data access, or misinformation through manipulated content. The stored XSS could be leveraged to target users with phishing or social engineering attacks, potentially leading to broader network compromise if users have elevated privileges. Additionally, the reputational damage from exploitation in sensitive religious contexts could be significant, affecting trust and community relations. The vulnerability's requirement for high privileges and user interaction somewhat limits mass exploitation but does not eliminate targeted attacks. European organizations with diverse user bases and multilingual needs might be more inclined to use this product, increasing exposure.

1. Immediate mitigation should include restricting user input fields to allow only safe characters and implementing robust input validation and output encoding to neutralize potentially malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser. 3. Monitor and audit user-generated content for suspicious scripts or payloads. 4. Limit privileges of users who can submit content to reduce the risk of high-privilege exploitation. 5. Educate users about the risks of interacting with unexpected or suspicious content. 6. Since no patches are currently linked, organizations should contact the vendor for updates or consider temporary removal or replacement of the vulnerable component. 7. Implement web application firewalls (WAFs) with rules to detect and block XSS payloads targeting this application. 8. Regularly review and update security policies around third-party application usage, especially those handling sensitive or culturally significant content.
