CVE-2025-48092 identifies a reflected Cross-site Scripting (XSS) vulnerability in the Fix Multiple Redirects plugin developed by jurajpuchky, affecting versions up to and including 1.2.3. The vulnerability arises from improper neutralization of input during web page generation, allowing malicious actors to inject and execute arbitrary scripts in the context of a victim's browser. This occurs because the plugin fails to adequately sanitize user-supplied input before reflecting it back in HTTP responses, enabling attackers to craft URLs that, when visited by users, execute malicious JavaScript code. The vulnerability is exploitable remotely over the network without requiring authentication, but it does require user interaction, such as clicking a malicious link. The CVSS 3.1 base score of 7.1 indicates a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). Although no known exploits are currently reported in the wild, the vulnerability poses significant risks including session hijacking, credential theft, unauthorized actions, and potential website defacement or redirection to malicious sites. The plugin is commonly used to manage multiple redirects in web applications, particularly in WordPress environments, making it a valuable target for attackers aiming to compromise web infrastructure or user trust.

For European organizations, this vulnerability can lead to several adverse impacts. Successful exploitation can result in theft of sensitive user data such as session cookies, enabling attackers to impersonate users and escalate privileges. It can also facilitate phishing attacks by redirecting users to malicious sites or displaying fraudulent content. The integrity of web applications may be compromised, leading to unauthorized actions or data manipulation. Availability could be affected if attackers use the vulnerability to inject disruptive scripts or cause denial-of-service conditions. Given the widespread use of WordPress and its plugins across Europe, organizations in sectors such as e-commerce, government, finance, and media are particularly at risk. The reputational damage and potential regulatory consequences under GDPR for data breaches further amplify the impact. Although no active exploits are reported, the ease of exploitation and broad attack surface necessitate urgent attention.

Organizations should immediately verify if they use the Fix Multiple Redirects plugin version 1.2.3 or earlier and upgrade to a patched version once available. In the absence of an official patch, temporarily disabling the plugin can mitigate risk. 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. Conduct thorough security testing, including automated scanning and manual code review, focusing on input handling in redirect-related functionalities. Educate users about the risks of clicking suspicious links and implement multi-factor authentication to reduce the impact of session hijacking. Monitor web server logs for unusual redirect patterns or suspicious URL parameters. Finally, maintain an incident response plan to quickly address any exploitation attempts.
