Deeper analysis

CVE-2025-49043 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the LambertGroup Magic Responsive Slider and Carousel WordPress plugin (magic_carousel). This issue affects all versions from n/a through 1.6, as published on 2026-01-22. 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 high severity due to its network accessibility and scope change.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity, requiring no privileges but relying on user interaction, such as clicking a malicious link. Successful exploitation allows injection of arbitrary scripts that reflect back in the victim's browser context, potentially leading to low-level impacts on confidentiality, integrity, and availability within the changed scope, such as session hijacking or phishing within the WordPress site.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/magic_carousel/vulnerability/wordpress-magic-responsive-slider-and-carousel-wordpress-plugin-1-6-reflected-cross-site-scripting-xss-vulnerability?_s_id=cve documents the Reflected XSS issue specific to plugin version 1.6, serving as a key reference for security practitioners to review detailed analysis and recommended mitigations.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and sanitization of untrusted input to block the reflected script payloads that exploit the plugin's lack of neutralization.

SI-15 Information Output Filtering good match
prevent

Requires filtering or encoding of information outputs so that attacker-supplied scripts cannot be reflected and executed in the victim's browser context.

SI-3 Malicious Code Protection partial match
preventdetect

Provides mechanisms to detect and block malicious code (scripts) delivered via the reflected XSS vector before or during page generation.
