CVE-2026-28101 is classified as a high-severity vulnerability due to its CVSS score of 7.1. This vulnerability allows improper neutralization of input during web page generation, specifically resulting in Reflected Cross-site Scripting (XSS) in the LambertGroup UberSlider MouseInteraction plugin. The affected versions include those up to 2.3, making this a significant concern for users of the plugin.
The vulnerability was published on March 5, 2026, and has been marked as deferred. Despite its high CVSS score, it is essential to note that there are currently no known exploits or active exploitation cases associated with this vulnerability.
Risk to organizations includes potential unauthorized actions on users' behalf through the exploitation of this vulnerability. Attackers may leverage XSS to gain access to sensitive information, create phishing attacks, or perform other malicious actions.
Organizations should prioritize patching this vulnerability immediately to mitigate associated risks. Ensuring that all instances of the UberSlider MouseInteraction plugin are updated is critical to maintaining the security of web applications.
Vulnerability Details
The CVE-2026-28101 vulnerability is a result of improper input handling, leading to Cross-site Scripting (XSS). This vulnerability affects the UberSlider MouseInteraction plugin and is present in versions from not available through 2.3. The CWE classification for this vulnerability is CWE-79, indicating a failure to properly sanitize input.
The vulnerability is characterized by a CVSS score of 7.1, signifying a high level of severity. The attack vector is categorized as network-based, meaning that an attacker does not need physical access to exploit this vulnerability. The attack complexity is low, and no special privileges are required, although user interaction is necessary to trigger the XSS payload.
Technical Analysis
The root cause of the vulnerability stems from the plugin's failure to properly neutralize user input during web page generation. This oversight allows an attacker to inject malicious scripts, which can be executed in the context of the victim's browser.
The attack vector is through network requests, where the attacker must lure the victim to interact with a crafted URL that includes the malicious script. The attack complexity is low due to the straightforward nature of the XSS payload. No privileges are required for exploitation, but user interaction is necessary to execute the attack.
The confidentiality, integrity, and availability impacts are all classified as low. While the attacker can manipulate user sessions or potentially steal sensitive data, the overall impact is limited to the affected user session without broader system compromise.
Risk & Impact Analysis
Organizations using the affected UberSlider MouseInteraction plugin should assess their exposure to this vulnerability, especially given its high CVSS score. The potential for users to be tricked into executing harmful scripts poses a real risk, particularly for applications handling sensitive data.
The blast radius of this vulnerability can be significant if the application is widely used. Users interacting with the affected plugin may unknowingly execute malicious scripts, leading to unauthorized access or data theft.
Given the current lack of public exploits and the deferred status of this vulnerability, organizations still need to act promptly to address it. The urgency for patching is high, and organizations should integrate remediation into their patch cycle.
