CVE-2025-47475 is a medium-severity vulnerability classified under CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the JupiterX Core plugin developed by Artbees, specifically versions up to and including 4.8.11. The flaw allows an attacker to inject malicious scripts that are stored persistently within the application, leading to Stored XSS. Stored XSS occurs when malicious input is saved by the application and later rendered in web pages viewed by other users without proper sanitization or encoding. The CVSS 3.1 base score of 6.5 reflects a medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), user interaction (UI:R), scope changed (S:C), and low impact on confidentiality, integrity, and availability (C:L/I:L/A:L). The vulnerability requires an attacker to have some level of authenticated access (privileges) and for the victim user to interact with the malicious content for exploitation. The scope change indicates that the vulnerability affects resources beyond the vulnerable component, potentially impacting other parts of the system or users. No known exploits are currently reported in the wild, and no patch links are provided yet, suggesting that mitigation or fixes may still be pending or in development. The vulnerability is significant because Stored XSS can lead to session hijacking, defacement, phishing, or distribution of malware to users of affected websites. Given that JupiterX Core is a WordPress theme/plugin component, it is commonly used in website development, especially for creative and business sites, making the attack surface potentially broad.

For European organizations, this vulnerability poses a risk primarily to websites using the JupiterX Core plugin. Exploitation could lead to unauthorized script execution in the browsers of site visitors or administrators, potentially compromising user sessions, stealing sensitive information, or enabling further attacks such as privilege escalation or malware distribution. This can damage organizational reputation, lead to data breaches involving personal data protected under GDPR, and cause operational disruptions. Since the vulnerability requires some level of authenticated access and user interaction, internal users or contributors to the website could be targeted or inadvertently facilitate exploitation. The scope change in the CVSS vector suggests that the impact could extend beyond the immediate plugin, possibly affecting other integrated components or user accounts. European organizations with customer-facing websites or intranet portals built on WordPress using JupiterX Core are particularly at risk. The lack of a patch at the time of publication increases exposure, especially for organizations that do not have robust monitoring or input validation controls. Additionally, regulatory implications under GDPR for data breaches involving personal data could result in financial penalties and loss of customer trust.

1. Immediate mitigation should include restricting access to the JupiterX Core plugin features to trusted and minimal necessary users to reduce the risk of an attacker injecting malicious scripts. 2. Implement strict input validation and output encoding on all user-supplied data within the affected plugin areas, even if a patch is not yet available. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected web pages. 4. Monitor web application logs and user activity for unusual behavior or attempts to inject scripts. 5. Regularly back up website data to enable recovery in case of compromise. 6. Stay updated with vendor advisories and apply patches promptly once released. 7. Conduct security awareness training for site administrators and content contributors to recognize phishing or suspicious activities that could facilitate exploitation. 8. Consider deploying Web Application Firewalls (WAF) with rules tailored to detect and block XSS payloads targeting JupiterX Core. 9. Review and harden user privilege assignments to ensure least privilege principles are enforced, minimizing the risk from compromised accounts.
