Deeper analysis

CVE-2026-28112, published on 2026-03-05, is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79. It affects the AllInOne - Banner Rotator WordPress plugin developed by LambertGroup, specifically versions from n/a through 3.8.

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). Remote attackers with network access can exploit it with low attack complexity and no required privileges, though it demands user interaction such as visiting a maliciously crafted URL. Exploitation enables limited impacts on confidentiality, integrity, and availability within a changed scope, allowing attackers to inject and execute arbitrary scripts in the context of a victim's browser.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and neutralization of untrusted input before it is used in web page generation, blocking the reflected XSS payload in the banner rotator plugin.

SI-15 Information Output Filtering good match
prevent

Requires filtering of information outputs to remove or encode script content, preventing execution of attacker-supplied reflected XSS in the victim's browser context.

SI-3 Malicious Code Protection partial match
preventdetect

Can enforce malicious-code detection and blocking mechanisms that recognize and stop reflected script injection attempts targeting the vulnerable plugin endpoints.
