Deeper analysis
CVE-2026-28100 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the UberSlider PerpetuumMobile WordPress plugin (uberSlider_perpetuummobile) developed by LambertGroup. The issue affects all versions of the plugin from n/a through 2.3 inclusive, allowing malicious input to be reflected in dynamically generated web pages without proper neutralization.
The vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network accessibility, low attack complexity, no required privileges, and user interaction such as clicking a crafted link. Remote attackers can exploit it by tricking authenticated or unauthenticated users into interacting with malicious payloads, achieving script execution in the victim's browser context with changed scope, resulting in low impacts to confidentiality, integrity, and availability, such as session hijacking or minor data manipulation.

Directly requires validation and neutralization of untrusted input before it is reflected in dynamically generated web pages, blocking the reflected XSS payload in uberSlider_perpetuummobile.
Requires filtering or encoding of information output to users, preventing malicious scripts from being executed in the victim's browser context.
Enables malicious-code detection mechanisms (e.g., WAF rules or content filters) that can identify and block reflected XSS attempts before they reach the plugin code.
