CVE-2025-23081 is a medium-severity vulnerability affecting the Wikimedia Foundation's Mediawiki DataTransfer Extension. This security flaw allows for Cross-Site Request Forgery (CSRF) and Cross-Site Scripting (XSS) attacks. The vulnerability arises from improper input neutralization during web page generation, which can lead to unauthorized actions being executed on behalf of users.
This vulnerability is classified with a CVSS score of 6.1, indicating a medium severity level. The attack vector is network-based with low complexity, requiring no privileges but necessitating user interaction. The potential impact on confidentiality and integrity is low, while availability is not affected. This situation represents a risk to organizations as attackers may leverage it to execute unauthorized actions within user sessions.
The vulnerability affects versions of the DataTransfer Extension prior to 1.39.11, 1.41.3, and 1.42.2. As this issue is currently deferred, organizations should still prioritize patching as soon as vendor updates are available to ensure protection against possible exploitation.
Given the nature of this vulnerability and its potential impact, organizations should address this in their priority patch cycle. Remediation steps should be taken to secure affected systems and prevent potential exploitation.
Vulnerability Details
The official description states that this vulnerability allows Cross-Site Request Forgery (CSRF) and improper neutralization of input during web page generation (XSS). The affected versions are Mediawiki - DataTransfer Extension: from 1.39.X before 1.39.11, from 1.41.X before 1.41.3, and from 1.42.X before 1.42.2.
This vulnerability has been classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-352 (Cross-Site Request Forgery). The publication date was January 14, 2025, and it was last modified on April 15, 2026.
Technical Analysis
The root cause of CVE-2025-23081 stems from improper validation of user inputs, leading to the potential for CSRF and XSS attacks. The attack vector is primarily network-based, allowing attackers to exploit the vulnerability remotely.
The attack complexity is low, indicating that an attacker does not need extensive technical skills to exploit the vulnerability. No privileges are required to initiate the attack, but user interaction is necessary, making it a social engineering challenge.
In terms of impacts, the confidentiality and integrity of data may be compromised, while availability remains unaffected. Organizations need to monitor for any exploitation attempts as part of their security measures.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-23081 is significant due to its potential to allow unauthorized actions on behalf of users. Organizations utilizing the Mediawiki DataTransfer Extension need to be aware of the blast radius of this vulnerability, as it could facilitate unauthorized access to sensitive data.
The urgency assessment indicates this should be addressed in priority patch cycles. While the CVSS score is medium, the potential for exploitation exists, and organizations should ensure that they are prepared to respond to any emerging threats.
