Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-15 requires filtering of information output during web page generation, directly preventing reflected XSS by neutralizing untrusted input before rendering.

prevent

SI-10 enforces input validation at entry points, blocking malicious payloads like XSS scripts from being processed in the WordPress plugin.

prevent

SI-2 mandates timely remediation of flaws such as this reflected XSS vulnerability in the Better User Shortcodes plugin through patching.

MITRE ATT&CK Enterprise TechniquesAI

T1189 Drive-by Compromise Initial Access
Adversaries may gain access to a system through a user visiting a website over the normal course of browsing.
Why these techniques?

Reflected XSS enables drive-by compromise via malicious links that execute scripts in victim browsers.

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

NVD Description

Deeper analysisAI

CVE-2025-22594 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Better User Shortcodes WordPress plugin by hccoder. The issue affects the plugin from unspecified initial versions through version 1.0 inclusive. Published on January 9, 2025, it carries a CVSS v3.1 base score of 7.1.

Attackers can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L), requiring no privileges (PR:N) but user interaction (UI:R), such as clicking a malicious link. Exploitation changes scope (S:C) and enables low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), allowing arbitrary script execution in the victim's browser context.
