CVE-2026-28112 is classified as a reflected Cross-site Scripting (XSS) vulnerability found in the LambertGroup AllInOne - Banner Rotator plugin. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users. The issue specifically affects versions of the Banner Rotator plugin up to 3.8. With a CVSS score of 7.1, this vulnerability is categorized as high severity, indicating significant risk to organizations using this plugin.
Organizations utilizing the AllInOne - Banner Rotator plugin should be aware of the potential for exploitation. The reflected XSS can lead to unauthorized actions being performed in the context of victim users, which may include accessing sensitive information or manipulating user sessions. Immediate action is necessary, as the attack vector is network-based and requires user interaction, albeit with low complexity.
Given the nature of this vulnerability, it is crucial for organizations to prioritize patching and remediation efforts. Organizations should assess their use of the affected plugin and take necessary steps to mitigate risks while awaiting an official fix.
Understanding the urgency of this vulnerability is essential. Organizations should address this issue in their priority patch cycle to reduce potential exposure and safeguard their users against possible exploitation.
Vulnerability Details
The vulnerability described in CVE-2026-28112 arises from improper neutralization of input during web page generation, leading to reflected XSS. This vulnerability is classified under CWE-79. The CVSS 3.1 vector string is AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating a network attack vector, low attack complexity, no privileges required, user interaction required, and a change in scope.
Organizations should be aware that this vulnerability was published on March 5, 2026, and is currently marked as deferred. The lack of an immediate patch increases the urgency for organizations to take action.
Technical Analysis
The root cause of CVE-2026-28112 is the failure to properly sanitize user input in the web page generation process, allowing attackers to inject scripts that execute in the context of the victim's browser. The attack vector is network-based, requiring user interaction to trigger the vulnerability. Given the low complexity of the attack, it poses a significant risk.
The vulnerability requires no special privileges, making it accessible to any user visiting the affected web page. User interaction is necessary, as the malicious script must be executed through a crafted URL or user action. The impacts on confidentiality, integrity, and availability are all rated as low, but the potential for user data exposure remains a concern.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-28112 is significant, particularly for organizations that rely on the AllInOne - Banner Rotator plugin for user engagement and content presentation. The potential for attackers to exploit this vulnerability to perform actions in the context of user sessions creates a substantial blast radius, affecting not only the organization but also its users.
With the CVSS score of 7.1, organizations should assess this vulnerability as high priority. The urgency for remediation is compounded by the potential for exploitation in the wild, emphasizing the need for immediate attention.
