CVE-2025-5340: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in smartwpress Music Player for Elementor – Audio Player & Podcast Player
The Music Player for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘album_buy_url’ parameter in all versions up to, and including, 2.4.6 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.
AI Analysis
Technical Summary
CVE-2025-5340 is a medium-severity Stored Cross-Site Scripting (XSS) vulnerability affecting the Music Player for Elementor – Audio Player & Podcast Player WordPress plugin developed by smartwpress. The vulnerability arises from improper neutralization of input during web page generation, specifically through the 'album_buy_url' parameter. Versions up to and including 2.4.6 of this plugin do not sufficiently sanitize or escape user-supplied input in this parameter, allowing an authenticated attacker with Contributor-level privileges or higher to inject arbitrary JavaScript code into pages. Since the injected scripts are stored, they execute whenever any user accesses the compromised page, potentially leading to session hijacking, privilege escalation, or other malicious activities. The CVSS v3.1 base score is 6.4, reflecting a network attack vector with low attack complexity, requiring privileges but no user interaction, and impacting confidentiality and integrity with a scope change. No known exploits are currently reported in the wild, but the vulnerability's presence in a popular WordPress plugin used for audio and podcast playback makes it a relevant threat vector for websites relying on this plugin. The vulnerability is particularly concerning because Contributor-level users are often trusted content creators, so the attack surface includes many legitimate users who might be compromised or malicious. The lack of a patch link indicates that a fix may not yet be publicly available, increasing the urgency for mitigation.
Potential Impact
For European organizations, this vulnerability poses a significant risk to websites using the Music Player for Elementor plugin, especially those with multiple content contributors. Exploitation could lead to unauthorized script execution, enabling attackers to steal session cookies, deface websites, redirect users to malicious sites, or perform actions on behalf of other users. This can damage organizational reputation, lead to data breaches, and violate GDPR requirements concerning data protection and user privacy. Since the vulnerability requires authenticated access at Contributor level, organizations with collaborative content workflows are at higher risk. Attackers could leverage compromised accounts or social engineering to gain the necessary privileges. The scope change in the CVSS vector indicates that the vulnerability can affect resources beyond the initially compromised component, potentially impacting other parts of the web application. Given the widespread use of WordPress in Europe and the popularity of Elementor plugins, many small to medium enterprises, media outlets, and podcast producers could be affected. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers often reverse-engineer disclosed vulnerabilities to develop exploits rapidly.
Mitigation Recommendations
European organizations should take immediate steps to mitigate this vulnerability. First, monitor the smartwpress vendor channels and WordPress plugin repository for official patches or updates addressing CVE-2025-5340 and apply them promptly. Until a patch is available, restrict Contributor-level user permissions to trusted individuals only and review existing Contributor accounts for suspicious activity. Implement Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the 'album_buy_url' parameter. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected pages. Conduct regular security audits and code reviews of customizations involving the plugin. Additionally, educate content contributors about the risks of uploading or embedding untrusted URLs or scripts. Consider temporarily disabling or replacing the vulnerable plugin with alternative audio player solutions that have been verified as secure. Finally, maintain comprehensive logging and monitoring to detect any anomalous behavior indicative of exploitation attempts.
