CVE-2025-22585: Medium Vulnerability in themebon Ultimate Image Hover Effects

A medium-severity vulnerability has been identified in the themebon Ultimate Image Hover Effects plugin. This vulnerability allows improper neutralization of input during web page generation, specifically enabling DOM-Based Cross-site Scripting (XSS). Given the nature of XSS vulnerabilities, attackers may leverage this flaw to execute arbitrary scripts in the context of a user's browser, potentially compromising sensitive information and user interactions.

The CVSS score assigned to this vulnerability is 6.5, indicating a medium level of severity. This score reflects the potential impact on confidentiality, integrity, and availability, which are all rated as low. The vulnerability is present in versions of the plugin from n/a through 1.1.2, and it was published on January 7, 2025. Organizations utilizing the affected plugin should be aware of this vulnerability and evaluate the risks associated with its exploitation.

As of now, there are no known public exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, given the characteristics of XSS attacks, organizations should take this vulnerability seriously and prioritize patching to prevent potential exploitation. Organizations should address this in their priority patch cycle.

With the XSS vulnerability being classified under CWE-79, it is imperative for organizations to implement secure coding practices and validate user inputs to mitigate such risks. Organizations should prioritize patching immediately to protect against potential exploitation.

Vulnerability Details

The vulnerability described allows improper neutralization of input during web page generation, leading to DOM-Based XSS in the themebon Ultimate Image Hover Effects plugin. The affected versions range from n/a to version 1.1.2. This vulnerability was first published on January 7, 2025, and the CWE classification for this issue is CWE-79.

Technical Analysis

The root cause of this vulnerability stems from improper input handling within the plugin, allowing attackers to inject malicious scripts into web pages. The attack vector for this vulnerability is through network interactions, requiring low attack complexity and low privileges for exploitation. User interaction is required to trigger the exploit, which means that a victim must visit a maliciously crafted page to activate the attack.

The confidentiality, integrity, and availability impacts are all rated as low, suggesting that while the potential for abuse exists, the immediate consequences may be limited. However, the possibility of executing arbitrary scripts in the context of a user's session poses a significant risk to user data and application security.

Risk & Impact Analysis

This vulnerability poses a significant risk to organizations using the themebon Ultimate Image Hover Effects plugin, as it could allow attackers to manipulate user sessions and gain unauthorized access to user data. Organizations should schedule remediation of this vulnerability in their priority patch cycle to prevent potential exploitation. The blast radius of this vulnerability can extend to any users interacting with the affected plugin, making it crucial for organizations to assess their exposure and take proactive measures.

Given the CVSS score of 6.5, organizations should prioritize their response to this vulnerability. Though it has not been deemed actively exploited or included in the KEV catalog, the nature of XSS attacks means that organizations could face significant fallout if they do not address this vulnerability promptly.

Exploitation Status

Affected Versions

The affected versions of the themebon Ultimate Image Hover Effects plugin range from n/a to 1.1.2. Organizations using any of these versions should take immediate action to update their systems.
