CVE-2025-23651 describes an improper neutralization of input during web page generation, specifically allowing for reflected Cross-site Scripting (XSS) vulnerabilities in the adamskaat Scroll Top scroll-to-top-builder. This vulnerability affects Scroll Top versions from n/a through 1.3.3. The vulnerability has been assigned a CVSS score of 7.1, indicating a high severity level that requires immediate attention from security teams.
Organizations leveraging the Scroll Top plugin should be aware of the risks associated with this vulnerability. Risk to organizations includes potential unauthorized access to sensitive information through XSS attacks, which can lead to session hijacking, defacement, or redirection to malicious sites. Attackers may leverage this vulnerability to execute scripts in the context of users' sessions, posing a significant threat to the integrity of web applications.
The vulnerability was published on February 14, 2025, and while it is currently marked as deferred, the potential for exploitation remains. Organizations should prioritize patching immediately to mitigate any associated risks.
Given the nature of the vulnerability and its potential impact, it is crucial for security teams to assess their exposure and implement necessary measures to protect against potential exploitation.
Vulnerability Details
The vulnerability is classified as Cross-site Scripting (XSS), specifically CWE-79. The CVSS score of 7.1 indicates a high severity level, with the following vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. The attack vector is network-based, and it has low complexity with no privileges required for an attacker. User interaction is required for exploitation, which adds a layer of complexity.
The potential impacts include low confidentiality, integrity, and availability, which may allow attackers to inject malicious scripts that can be executed in the victims' browsers.
Technical Analysis
The root cause of CVE-2025-23651 is the improper handling of user input during the generation of web pages in the Scroll Top plugin. This oversight allows attackers to inject malicious scripts that could be executed in the context of the user’s session.
The attack vector is network-based, meaning that a successful attack can occur remotely without needing physical access to the target system. The complexity is low, with no privileges required for exploitation. However, user interaction is necessary, as the victim must click on a malicious link or visit a compromised web page.
The confidentiality, integrity, and availability impacts are rated low, indicating that while the risk is present, the actual damage may be limited depending on the context of the attack.
Risk & Impact Analysis
Organizations utilizing the Scroll Top plugin face a significant risk if this vulnerability is not addressed. The potential for reflected XSS could lead to unauthorized access to sensitive user data, manipulation of web content, and a compromised user experience. The blast radius could include any user who interacts with the affected web pages, thus broadening the scope of impact.
Organizations should assess their exposure to this vulnerability in light of their operational context and the potential for exploitation. The urgency for addressing this vulnerability is high, given the CVSS score and potential for real-world attacks.
With the lack of known exploits at this time, the focus should be on timely patch management and monitoring for any signs of exploitation as part of a comprehensive security strategy.
