CVE-2026-28102 is classified as a high-severity vulnerability affecting the LambertGroup UberSlider Classic plugin, specifically versions from n/a through 2.5. This vulnerability allows for improper neutralization of input during web page generation, leading to reflected Cross-site Scripting (XSS). The CVSS score of 7.1 indicates significant risk to organizations, particularly as this vulnerability can be exploited through network-based attacks with low complexity. As the severity level is high, organizations must prioritize patching immediately to prevent potential exploitation.
Risk to organizations includes the potential for attackers to execute arbitrary code in the context of the victim’s session. This can lead to unauthorized actions taken on behalf of users, compromising sensitive information. Given the nature of XSS vulnerabilities, the risk is amplified when users interact with the malicious payloads. The urgency for defenders is high due to the possibility of widespread exploitation.
Currently, there is no known public exploit for this vulnerability, nor has it been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant due to the potential for active exploitation in the future. The status of this vulnerability is deferred, but it still requires immediate attention from security teams.
Organizations should assess their usage of the UberSlider Classic plugin and implement necessary updates to mitigate the risk. Regular vulnerability assessments and patch management processes should be in place to address such vulnerabilities proactively.
Vulnerability Details
The CVE-2026-28102 vulnerability is characterized by incorrect input neutralization during web page generation, which allows for reflected XSS. The CVSS 3.1 score of 7.1 reflects its high severity, indicating the potential for significant impact on confidentiality, integrity, and availability. The vulnerability specifically affects the UberSlider Classic plugin from versions n/a through 2.5, as identified in the CVE publication.
Technical Analysis
The root cause of this vulnerability stems from improper neutralization of user input, allowing attackers to inject malicious scripts that are executed in the context of the victim's browser. The attack vector is network-based, requiring user interaction for successful exploitation. The attack complexity is rated as low, with no privileges required for an attacker to initiate the attack.
The impact of this vulnerability is classified as low across confidentiality, integrity, and availability, yet the actual risk can be significant depending on the context of use. Organizations using this plugin should be aware of potential data exposure and unauthorized actions that can occur as a result of successful XSS attacks.
Risk & Impact Analysis
The real-world risk of CVE-2026-28102 is notable, especially for organizations that rely on the UberSlider Classic plugin. Attackers may leverage this vulnerability to execute scripts in an unsuspecting user's browser, leading to session hijacking, data theft, or defacement of web pages. The blast radius can extend beyond the initial target if users share compromised pages or links.
Given the CVSS score and the current lack of exploitation indicators, organizations should still treat this vulnerability with urgency. Security teams must prioritize patching and hardening their defenses against potential attacks that exploit similar weaknesses. Maintaining a proactive security posture is essential to mitigate risks effectively.
