CVE-2025-25133

Vulnerability

Description

The WP Frontend Submit plugin for WordPress versions ≤1.1.0 is vulnerable to Reflected Cross-Site Scripting (XSS) due to improper neutralization of user-supplied input during web page generation. This allows attackers to inject arbitrary HTML and JavaScript code into the response, leading to script execution in the context of the victim's browser [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious link or URL that, when visited by a privileged user (such as an administrator), triggers the reflection of the injected script. The attack does not require authentication to initiate, but successful exploitation depends on the victim performing an action like clicking the link or submitting a form. This makes it suitable for mass-exploit campaigns targeting multiple websites [1].

Impact

Successful exploitation allows an attacker to execute arbitrary scripts in the victim's browser. This can result in various malicious activities, including redirecting users to phishing pages, injecting advertisements, stealing sensitive information like session tokens or login credentials, or modifying site content. The vulnerability is rated as High (CVSS 7.1) and is considered moderately dangerous, with potential for widespread abuse [1].

Mitigation

The vendor has not yet released a permanent patch, but immediate action is recommended. Users should update the plugin to a fixed version as soon as it becomes available. In the meantime, Patchstack provides a mitigation rule to block attacks until an official patch can be applied. If unable to update, seeking assistance from a hosting provider or web developer is advised [1].
