CVE-2025-50033: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Sparkle Themes Fitness Park
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Sparkle Themes Fitness Park allows DOM-Based XSS. This issue affects Fitness Park: from n/a through 1.1.1.
AI Analysis
Technical Summary
CVE-2025-50033 is a DOM-based Cross-site Scripting (XSS) vulnerability identified in the Sparkle Themes Fitness Park product, affecting versions up to 1.1.1. This vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the issue allows malicious actors to inject and execute arbitrary JavaScript code within the context of a user's browser session by manipulating the Document Object Model (DOM) without proper sanitization or encoding of user-supplied input. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), but requires the attacker to have some level of privileges (PR:L) and user interaction (UI:R) to trigger the exploit. The scope of the vulnerability is changed (S:C), meaning that exploitation can affect resources beyond the vulnerable component, potentially impacting the confidentiality, integrity, and availability of data across the affected system. The CVSS v3.1 base score is 6.5, indicating a medium severity level. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the potential for session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The lack of available patches at the time of publication increases the urgency for organizations to implement mitigations. The vulnerability affects web applications built on the Fitness Park theme, which is used primarily in fitness and wellness websites, potentially exposing user data and administrative controls to compromise via crafted URLs or malicious input fields that interact with the vulnerable DOM elements.
Potential Impact
For European organizations, especially those operating fitness, wellness, or health-related web platforms using the Sparkle Themes Fitness Park product, this vulnerability can lead to unauthorized access to sensitive user information, including personal health data, login credentials, and session tokens. The exploitation of this DOM-based XSS can facilitate further attacks such as phishing, account takeover, or injection of malicious scripts that compromise user trust and violate data protection regulations like GDPR. The integrity of web applications may be undermined, leading to defacement or manipulation of displayed content, which can damage brand reputation. Availability impacts may arise if injected scripts perform denial-of-service actions or disrupt normal user interactions. Given the medium severity and requirement for user interaction, the threat is moderate but significant enough to warrant immediate attention, particularly for organizations with high volumes of user traffic or those handling sensitive personal data. Failure to address this vulnerability could result in regulatory penalties, financial losses, and erosion of customer confidence within the European market.
Mitigation Recommendations
1. Immediate implementation of input validation and output encoding on all user-supplied data that interacts with the DOM to prevent injection of malicious scripts. Use secure JavaScript frameworks or libraries that automatically handle DOM sanitization. 2. Employ Content Security Policy (CSP) headers to restrict the execution of untrusted scripts and reduce the impact of potential XSS attacks. 3. Conduct thorough code reviews focusing on client-side scripts that manipulate the DOM based on user input, ensuring no unsafe dynamic HTML or JavaScript generation occurs. 4. Monitor web application logs and user behavior for signs of suspicious activity indicative of XSS exploitation attempts. 5. Educate users and administrators about the risks of clicking on untrusted links or submitting unverified input, as user interaction is required for exploitation. 6. Engage with Sparkle Themes for timely updates or patches and plan for rapid deployment once available. 7. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block DOM-based XSS payloads targeting Fitness Park themes. 8. Regularly test web applications with automated and manual penetration testing tools focusing on DOM XSS vectors to identify and remediate vulnerabilities proactively.
