The vulnerability identified as CVE-2025-23777 is a stored Cross-site Scripting (XSS) vulnerability in the Willows Consulting GDPR Personal Data Reports plugin. This issue arises from improper neutralization of input during web page generation, allowing attackers to execute arbitrary scripts in the context of users' browsers. The affected versions are all versions prior to and including 1.0.5.
With a CVSS score of 6.5, this vulnerability is classified as medium severity. The risk to organizations includes potential unauthorized access to personal data and manipulation of user sessions, which could lead to data breaches or reputational damage. As this vulnerability has been officially deferred, organizations should remain vigilant for future updates regarding its status.
Organizations should prioritize patching immediately, as the exploitation of this vulnerability can result in significant consequences if not addressed. Security teams must evaluate their configurations and ensure that their systems are updated to mitigate this risk.
The vulnerability has not been confirmed to have public exploits, but the potential for exploitation exists. Organizations utilizing the affected plugin should take proactive measures to secure their applications against such vulnerabilities.
Vulnerability Details
The official description notes that this vulnerability allows stored XSS through the Willows Consulting GDPR Personal Data Reports plugin. The CVSS vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, indicating a network attack vector, low attack complexity, low privileges required, and user interaction needed for exploitation.
The vulnerability falls under the CWE classification CWE-79, which pertains to improper neutralization of input during web page generation. The publication date is January 16, 2025.
Technical Analysis
The root cause of this vulnerability is the failure to properly sanitize user inputs during the generation of web pages within the plugin. By exploiting this flaw, attackers can inject malicious scripts that are stored and executed within the application, impacting all users who interact with the compromised pages.
The attack vector is network-based, requiring low attack complexity. Attackers need to possess low privileges and user interaction is required to trigger the execution of the injected script. The potential impacts include low confidentiality, integrity, and availability impacts, as the scripts can manipulate the content displayed to users.
Risk & Impact Analysis
The real-world risk of this vulnerability includes the possibility of unauthorized access to sensitive user data and the manipulation of user sessions through XSS attacks. This could lead to data breaches, loss of user trust, and potential regulatory penalties for failing to protect personal data.
Organizations should assess their risk levels based on the potential for exploitation and the sensitivity of the data involved. Given the CVSS score of 6.5, the urgency for remediation is medium, and organizations should schedule remediation in their patch cycles.
The potential blast radius of an exploitation incident could affect all users of the impacted plugin, leading to a wide-reaching impact across user accounts and data integrity.
