This vulnerability allows for improper neutralization of input during web page generation, specifically a stored Cross-site Scripting (XSS) vulnerability in the horiyuki Image Switcher plugin. The affected versions are from n/a through 0.1.1. With a CVSS score of 6.5, this vulnerability is classified as medium severity, indicating that while it is not critical, it poses a significant risk to users and systems.
Risk to organizations includes potential unauthorized access to sensitive information, data manipulation, and disruption of service. Attackers may leverage this vulnerability to execute arbitrary scripts in the context of the victim's browser, leading to data theft or session hijacking. Organizations should prioritize patching immediately.
As of now, there is no known publicly available exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) database. However, the existence of this vulnerability in a widely used plugin necessitates prompt attention. Organizations using the horiyuki Image Switcher plugin must schedule remediation as part of their security practices.
For those managing affected systems, immediate action is recommended to mitigate potential risks associated with this vulnerability.
Vulnerability Details
The CVE-2025-23940 vulnerability is classified under CWE-79, which indicates a failure to properly sanitize user input. The vulnerability affects the horiyuki Image Switcher plugin and allows stored XSS, which can impact confidentiality, integrity, and availability. The CVSS vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, with the details indicating a network attack vector, low attack complexity, and low privileges required.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input during the generation of web pages. Specifically, user input that is not sufficiently sanitized can lead to the execution of malicious scripts in the context of other users' sessions. The attack vector is primarily network-based, meaning that an attacker could exploit this vulnerability remotely.
The complexity of the attack is low, requiring minimal technical skill from the attacker. Privileges required are also low, allowing any authenticated user to exploit this vulnerability. User interaction is required as an unsuspecting user must visit a page containing the injected script. The potential impacts include low confidentiality, integrity, and availability, as malicious scripts could steal data or perform actions on behalf of the user.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, particularly for organizations that rely on the horiyuki Image Switcher plugin for web functionality. The potential for unauthorized access to sensitive user data and the ability to manipulate web applications presents a critical challenge. Vigilance is required to protect against the blast radius that could result from successful exploitation.
Organizations should assess their exposure to this vulnerability based on the usage of vulnerable versions of the plugin and prioritize remediation efforts based on the CVSS score and its implications.
