The CVE-2025-23851 vulnerability is categorized as a high-severity Cross-site Scripting (XSS) issue within the Khushwant Singh Coronavirus (COVID-19) Outbreak Data Widgets. Specifically, this vulnerability allows for reflected XSS attacks, which can be exploited by attackers to execute arbitrary scripts in the context of the user's browser. Given the nature of this vulnerability, it poses significant risks, especially to organizations relying on this plugin for disseminating COVID-19 data.
The vulnerability has a CVSS base score of 7.1, indicating a high level of severity. It is characterized by a low attack complexity and requires user interaction to be exploited, making it crucial for organizations to understand the potential impact on confidentiality, integrity, and availability.
Currently, this vulnerability is marked as deferred, and although it has not been actively exploited in the wild, organizations should remain vigilant. Immediate remediation is recommended to prevent exploitation.
Organizations should prioritize patching the affected versions of the plugin and assess their deployment to mitigate the risks associated with this vulnerability.
Vulnerability Details
The vulnerability is classified under CWE-79, which refers to improper neutralization of input during web page generation. This specific issue affects all versions of the Coronavirus (COVID-19) Outbreak Data Widgets plugin up to and including version 1.1.1.
The CVSS score of 7.1 signifies a high level of risk, primarily due to the potential for attackers to execute scripts in a user's browser, which can lead to unauthorized actions taken on behalf of the user.
Published on February 14, 2025, this vulnerability is a reminder for organizations to maintain updated security practices and to monitor for any changes in their plugins that could introduce similar vulnerabilities.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input during the generation of web pages. Attackers can exploit this flaw by crafting malicious input that is processed by the application, leading to the injection of harmful scripts.
The attack vector is primarily network-based, meaning that an attacker can perform this exploit remotely without physical access to the target system. The attack complexity is rated as low, which means that it does not require any specialized skills or resources for an attacker to exploit the vulnerability.
No privileges are required for exploitation, and the user must interact with the malicious content, highlighting the importance of user awareness and caution when dealing with untrusted sources.
Although the confidentiality, integrity, and availability impacts are rated as low, organizations must recognize that even low-impact vulnerabilities can lead to significant consequences if exploited in conjunction with other vulnerabilities.
Risk & Impact Analysis
This vulnerability poses a real-world risk to organizations, especially those that rely on the Coronavirus (COVID-19) Outbreak Data Widgets for disseminating critical data. The potential for reflected XSS attacks can undermine user trust and lead to unauthorized access to sensitive user data.
The blast radius for exploitation could be significant, particularly if the widgets are embedded in high-traffic public-facing websites. Attackers leveraging this vulnerability can manipulate user experiences, leading to data theft, phishing attempts, or further exploitation of user accounts.
Organizations should assess this vulnerability’s urgency based on its CVSS score and the potential for exploitation. Given the high severity rating and the ease of exploitation, immediate action is recommended to patch the vulnerability.
