CVE-2025-48092 identifies a reflected Cross-site Scripting (XSS) vulnerability in the Fix Multiple Redirects plugin by jurajpuchky, affecting all versions up to and including 1.2.3. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious JavaScript code that is reflected back to the victim's browser. This reflected XSS can be triggered when a user clicks on a crafted URL containing malicious payloads. The vulnerability does not require authentication (AV:N), has low attack complexity (AC:L), and requires user interaction (UI:R), with a scope change (S:C) indicating that the vulnerability can affect resources beyond the vulnerable component. The impact includes partial loss of confidentiality, integrity, and availability (C:L/I:L/A:L), as attackers can steal session cookies, perform actions on behalf of users, or cause denial of service conditions. Although no exploits are currently known in the wild, the high CVSS score (7.1) reflects the potential severity. The plugin is commonly used in WordPress environments to manage multiple redirects, making it a target for attackers aiming to compromise websites or their users. The vulnerability was reserved in May 2025 and published in October 2025, but no official patch links are currently available, indicating that mitigation may require temporary workarounds or monitoring until a fix is released.

For European organizations, this vulnerability poses a significant risk to websites using the Fix Multiple Redirects plugin, particularly those that handle sensitive user data or provide critical services. Successful exploitation can lead to session hijacking, unauthorized actions performed in the context of authenticated users, and potential defacement or redirection to malicious sites. This can damage organizational reputation, lead to data breaches, and disrupt service availability. Given the reflected nature of the XSS, phishing campaigns can be enhanced by embedding malicious links that exploit this vulnerability. The impact is heightened for organizations in sectors such as finance, healthcare, and e-commerce, where trust and data integrity are paramount. Additionally, regulatory frameworks like GDPR impose strict requirements on data protection, and exploitation could result in compliance violations and financial penalties. The lack of a current patch increases the urgency for organizations to implement compensating controls to mitigate risk.

Organizations should immediately inventory their web assets to identify installations of the Fix Multiple Redirects plugin and verify the version in use. Until an official patch is released, consider disabling the plugin or removing it if it is not essential. Employ Web Application Firewalls (WAFs) configured to detect and block reflected XSS payloads, particularly those targeting redirect parameters. Implement strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts. Conduct thorough input validation and output encoding on all user-supplied data, especially URL parameters involved in redirects. Educate users and administrators about the risks of clicking on suspicious links. Monitor web server logs for unusual redirect patterns or repeated attempts to exploit the vulnerability. Once a patch becomes available, prioritize its deployment across all affected systems. Additionally, consider deploying runtime application self-protection (RASP) solutions to detect and prevent exploitation attempts in real time.
