Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-15 mandates information output filtering, directly addressing the improper neutralization of input during web page generation that enables reflected XSS in the ePermissions plugin.

prevent

SI-10 requires validation of information inputs, preventing malicious XSS payloads from being accepted and reflected unsanitized in the vulnerable WordPress plugin.

prevent

SI-2 ensures timely flaw remediation, such as patching the ePermissions plugin versions <=1.2 to eliminate the reflected XSS vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1566.002 Spearphishing Link Initial Access
Adversaries may send spearphishing emails with a malicious link in an attempt to gain access to victim systems.
T1204.001 Malicious Link Execution
An adversary may rely upon a user clicking a malicious link in order to gain execution.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
Why these techniques?

Reflected XSS vulnerability explicitly requires user interaction via clicking a malicious link to deliver and execute arbitrary JavaScript scripts in the victim's browser context.

NVD Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in mobde3net ePermissions epermissions allows Reflected XSS.This issue affects ePermissions: from n/a through <= 1.2.

Deeper analysisAI

CVE-2025-23635 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the ePermissions WordPress plugin developed by mobde3net. The issue affects ePermissions versions from n/a through 1.2 inclusive, allowing malicious input to be reflected without proper sanitization during web page generation.

With 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), the vulnerability can be exploited remotely over the network with low attack complexity and no required privileges, though it needs user interaction such as clicking a malicious link. Attackers can deliver reflected XSS payloads via crafted inputs, executing arbitrary scripts in the context of a victim's browser when accessing the affected site, potentially leading to low impacts on confidentiality, integrity, and availability, such as limited data exposure or site defacement.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/epermissions/vulnerability/wordpress-epermissions-plugin-1-2-reflected-cross-site-scripting-xss-vulnerability?_s_id=cve documents the Reflected XSS vulnerability in ePermissions version 1.2, providing details for WordPress site administrators on identification and response.
