Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SC-23 enforces session authenticity mechanisms like anti-CSRF tokens, directly preventing forged requests that store XSS payloads in the vulnerable WordPress plugin.
SI-10 requires validation of inputs prior to storage, blocking malicious XSS payloads from being accepted and stored via the CSRF vector.
SI-15 mandates output filtering to neutralize stored XSS payloads before they are rendered and executed in users' browsers.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The CSRF-to-stored-XSS vulnerability in a public-facing WordPress plugin directly enables exploitation of public-facing web applications (T1190) and facilitates client-side JavaScript execution via the injected XSS payload (T1059.007).

Deeper analysisAI
CVE-2025-26543 is a Cross-Site Request Forgery (CSRF) vulnerability in the Simple Responsive Menu WordPress plugin developed by Pukhraj Suthar, which allows for Stored XSS. The vulnerability affects all versions of the plugin from n/a through 2.1 inclusive.
The vulnerability can be exploited by unauthenticated attackers (PR:N) over the network (AV:N) with low complexity (AC:L), though it requires user interaction (UI:R). An attacker can trick an authenticated user, such as a site administrator, into submitting a malicious request that stores an XSS payload on the site. Exploitation changes scope (S:C) and results in low impacts to confidentiality, integrity, and availability (C:L/I:L/A:L), yielding a CVSS v3.1 base score of 7.1.
