CVE-2025-48097 identifies a Reflected Cross-site Scripting (XSS) vulnerability in the Shiva WSAnalytics plugin, specifically versions up to and including 1.1.2. This vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code that is reflected back to the victim's browser. When a victim accesses a crafted URL or interacts with a manipulated input field, the malicious script executes in the context of the victim's browser session. This can lead to theft of sensitive information such as authentication cookies, session tokens, or other private data, as well as unauthorized actions performed on behalf of the user. WSAnalytics is a plugin designed to integrate Google Analytics data and dashboards into web applications, commonly used in WordPress environments. The vulnerability does not require authentication or prior user interaction beyond visiting a malicious link, making it relatively easy to exploit. No CVSS score has been assigned yet, and no public exploits have been reported. The vulnerability was reserved in May 2025 and published in October 2025. The lack of available patches at the time of disclosure increases the urgency for organizations to implement interim mitigations such as input sanitization and Content Security Policy (CSP) enforcement.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of user data and web sessions. Attackers exploiting this vulnerability can hijack user sessions, steal credentials, or perform unauthorized actions within the affected web application. This can lead to data breaches, reputational damage, and potential regulatory penalties under GDPR if personal data is compromised. The availability impact is generally low, as XSS typically does not cause denial of service but can be leveraged as a stepping stone for further attacks. Organizations relying on WSAnalytics for web analytics and reporting may face operational disruptions if attackers manipulate dashboards or inject misleading data. The risk is heightened for organizations with public-facing web portals that integrate this plugin, especially those handling sensitive customer or employee data. The absence of known exploits in the wild currently limits immediate impact but does not preclude future exploitation once the vulnerability becomes widely known.

1. Monitor Shiva's official channels for patches addressing CVE-2025-48097 and apply them promptly upon release. 2. Until patches are available, implement strict input validation and output encoding on all user-supplied data that is reflected in web pages, particularly in parameters handled by WSAnalytics. 3. Deploy a robust Content Security Policy (CSP) to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Use web application firewalls (WAFs) with updated signatures to detect and block malicious payloads targeting this vulnerability. 5. Conduct regular security assessments and penetration testing focused on XSS vulnerabilities in web applications using WSAnalytics. 6. Educate developers and administrators on secure coding practices and the risks associated with reflected XSS. 7. Review and limit the exposure of analytics dashboards to authenticated and authorized users only, reducing the attack surface. 8. Implement HTTP-only and Secure flags on cookies to mitigate session theft risks.
