CVE-2025-48094 identifies a reflected Cross-site Scripting (XSS) vulnerability in the Magic Slider plugin developed by LambertGroup, affecting all versions up to and including 2.2. The 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 users without adequate sanitization. This flaw enables an attacker to craft a specially designed URL or input that, when visited or submitted by a victim, executes arbitrary scripts in the victim's browser context. The CVSS 3.1 base score of 6.1 reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The impact affects confidentiality and integrity (C:L/I:L) but not availability (A:N). Although no public exploits have been reported, the vulnerability is significant because XSS can be used for session hijacking, phishing, or delivering malware. The Magic Slider plugin is commonly used in WordPress websites to create image sliders, and its widespread use in various industries increases the attack surface. The vulnerability was reserved in May 2025 and published in January 2026, indicating a recent discovery. No official patches or fixes are currently linked, so users must monitor vendor advisories. The vulnerability's exploitation requires that a victim interacts with a malicious link or input, which can be delivered via email, social media, or other vectors. The reflected nature of the XSS means it does not persist on the server but can still be leveraged for targeted attacks.

For European organizations, this vulnerability poses a moderate risk primarily to websites using the Magic Slider plugin, especially those handling sensitive user data or providing critical services. Successful exploitation can lead to theft of user credentials, session tokens, or other confidential information, undermining user trust and potentially leading to account compromise. The integrity of user interactions can be compromised by injecting misleading or malicious content, facilitating phishing or social engineering attacks. Although availability is not directly impacted, reputational damage and regulatory consequences under GDPR could be significant if personal data is exposed or abused. Industries such as e-commerce, media, and government portals that rely on WordPress and its plugins are particularly vulnerable. The requirement for user interaction limits mass exploitation but targeted spear-phishing campaigns could be effective. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability becomes widely known.

European organizations should take proactive steps to mitigate this vulnerability. First, monitor LambertGroup’s official channels for patches or updates to Magic Slider and apply them promptly once available. Until patches are released, consider disabling or replacing the Magic Slider plugin with alternative, secure slider solutions. Implement strict input validation and output encoding on all user-supplied data to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. Conduct regular security audits and penetration testing focusing on web application vulnerabilities, including XSS. Educate users and staff about the risks of clicking unknown or suspicious links to reduce the likelihood of successful exploitation. Additionally, web application firewalls (WAFs) can be configured to detect and block common XSS attack patterns. Maintain up-to-date backups and incident response plans to quickly recover from any potential compromise. Finally, ensure compliance with GDPR by protecting user data and reporting any breaches promptly.
