Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SC-23 enforces mechanisms to protect communications session authenticity, directly mitigating CSRF by preventing forged requests from exploiting valid authenticated sessions in the EmailShroud plugin.

prevent

SI-10 requires validation of information inputs like CSRF tokens, preventing unauthorized forged requests that could trigger reflected XSS in the vulnerable WordPress plugin.

prevent

SI-15 filters information outputs to block reflected XSS payloads delivered via the CSRF vulnerability in EmailShroud.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
Why these techniques?

The CSRF to reflected XSS vulnerability in a public-facing WordPress plugin directly enables exploitation of public-facing applications (T1190). The reflected XSS payload allows an attacker to inject and execute arbitrary JavaScript in the victim's browser context (T1059.007).

NVD Description

Cross-Site Request Forgery (CSRF) vulnerability in Oddthinking EmailShroud emailshroud allows Reflected XSS.This issue affects EmailShroud: from n/a through <= 2.2.1.

Deeper analysisAI

CVE-2025-23456 is a Cross-Site Request Forgery (CSRF) vulnerability in the Oddthinking EmailShroud WordPress plugin that allows Reflected Cross-Site Scripting (XSS). This issue affects EmailShroud versions from n/a through <= 2.2.1 and is associated with CWE-352.

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). Any network-based attacker without privileges can exploit it by tricking an authenticated user into performing an unintended action via a forged request, requiring user interaction such as clicking a malicious link. Successful exploitation enables reflected XSS, resulting in low impacts to confidentiality, integrity, and availability with a changed scope.
