Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Enforces filtering of reflected inputs prior to web page generation, directly neutralizing malicious scripts to prevent XSS execution in the WP Frontend Submit plugin.

prevent

Validates user inputs to block malicious payloads before they are processed and reflected by the vulnerable plugin.

prevent

Requires timely patching of the WP Frontend Submit plugin to remediate the improper input neutralization flaw across affected versions.

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.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
Why these techniques?

The reflected XSS allows crafting malicious links for phishing delivery (T1566.002) and arbitrary browser script execution enabling web session cookie theft for hijacking (T1539).

NVD Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in newbiesup WP Frontend Submit wp-frontend-submit allows Reflected XSS.This issue affects WP Frontend Submit: from n/a through <= 1.1.0.

Deeper analysisAI

CVE-2025-25133 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-Site Scripting (XSS), in the WP Frontend Submit plugin (wp-frontend-submit) developed by newbiesup for WordPress. This issue affects all versions of the plugin from n/a through 1.1.0. The vulnerability carries a CVSS v3.1 base score of 7.1, with a vector of AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating network accessibility, low attack complexity, no required privileges, user interaction needed, changed scope, and low impacts on confidentiality, integrity, and availability.

Attackers can exploit this Reflected XSS flaw by crafting malicious inputs that are reflected back in web page generation without proper neutralization, tricking authenticated or unauthenticated users into interacting with a malicious link or payload via a phishing vector. No privileges are required (PR:N), but user interaction (UI:R) is necessary, such as clicking a link. Successful exploitation allows execution of arbitrary scripts in the victim's browser context, potentially leading to low-level impacts like session hijacking, data theft, or page manipulation, with scope change (S:C) enabling actions beyond the vulnerable component.

Patchstack provides details on this vulnerability, including mitigation guidance, via their advisory at https://patchstack.com/database/Wordpress/Plugin/wp-frontend-submit/vulnerability/wordpress-indeed-api-plugin-0-5-csrf-to-settings-change-vulnerability-2?_s_id=cve. Security practitioners should update to a patched version if available or apply workarounds as recommended in the advisory.
