CVE-2026-22714 is a low-severity vulnerability identified within The Wikimedia Foundation Mediawiki - Monaco Skin, which allows improper neutralization of input during web page generation, specifically leading to Cross-Site Scripting (XSS) attacks. This vulnerability affects multiple versions of the Monaco Skin, specifically versions 1.45, 1.44, 1.43, and 1.39. Organizations utilizing these versions may be exposed to risks associated with XSS attacks, where attackers could potentially execute malicious scripts in user browsers.
The vulnerability has been assigned a CVSS score of 2.3, indicating it has low severity. While this may not pose an immediate critical threat, organizations must understand that the risk to organizations includes potential data theft or unauthorized actions performed on behalf of users. Therefore, it is important to assess the impact this vulnerability may have on your systems and user data.
Currently, there are no known exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, as the threat landscape evolves, organizations should remain vigilant and prioritize patching as part of their regular maintenance cycle.
Organizations should address this vulnerability in their priority patch cycle to mitigate potential risks associated with XSS attacks. Ensuring the use of the latest versions of affected software can help in reducing exposure to such vulnerabilities.
Vulnerability Details
The vulnerability described in CVE-2026-22714 is categorized as an improper neutralization of input during web page generation, leading to Cross-Site Scripting (XSS). The specific nature of this vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. This issue primarily affects The Wikimedia Foundation Mediawiki - Monaco Skin across several versions, namely 1.45, 1.44, 1.43, and 1.39.
The CVSS score assigned to this vulnerability is 2.3, reflecting a low severity level. The low score is primarily due to the required user interaction for exploitation, as it necessitates that the victim user visits a compromised web page. The attack vector is classified as NETWORK, with low attack complexity, indicating that the exploitation method is relatively straightforward for an attacker to execute.
The vulnerability has a low impact on confidentiality and integrity, which means that while it may not lead to severe data breaches, it can still compromise the user experience and trust in the application. The issue has been categorized under CWE-79, which relates to improper neutralization of input during web page generation.
Technical Analysis
The root cause of CVE-2026-22714 stems from a failure to properly sanitize input data during the web page generation process in Mediawiki - Monaco Skin. Specifically, when users input data that is not adequately filtered or validated, it can result in malicious scripts being executed in the context of the web application.
The attack vector for this vulnerability is NETWORK-based, allowing attackers to exploit it remotely. The attack complexity is low, and it requires no privileges, meaning that any user can trigger the vulnerability through passive user interaction, such as clicking on a malicious link. The impact on confidentiality and integrity is rated as low, indicating that while sensitive information might not be directly compromised, malicious scripts could manipulate user sessions or redirect users to harmful sites.
Risk & Impact Analysis
Given the low CVSS score, the immediate risk to organizations from CVE-2026-22714 may seem minimal. However, the threat of Cross-Site Scripting vulnerabilities should not be underestimated. Attackers may leverage this vulnerability to execute scripts that can capture session cookies, redirect users to phishing sites, or perform actions on behalf of users without their consent.
Organizations should prioritize patching this vulnerability as part of their regular maintenance cycle. Although the exploitation status indicates that there are no known exploits at this time, the potential for future attacks exists, especially as attackers continuously look for vulnerabilities to exploit.
