CVE-2025-48105

Vulnerability

Overview

The Easy Flash Embed plugin for WordPress (versions up to and including 1.0) contains a Stored Cross-Site Scripting (XSS) vulnerability caused by improper neutralization of input during web page generation [1]. This means user-supplied input is not sanitized before being stored and later displayed on pages, allowing an attacker to inject arbitrary HTML and JavaScript code.

Exploitation

Method

The vulnerability requires a privileged user role to initiate the attack, and successful exploitation depends on user interaction such as clicking a malicious link or submitting a specially crafted form [1]. An attacker with the necessary privileges can inject malicious scripts that persist in the plugin's output, executing every time another user or visitor views the affected page.

Potential

Impact

A successful attack could allow malicious actors to inject arbitrary content such as redirects, advertisements, and other HTML payloads into the website [1]. These scripts execute in the context of the victim's session, potentially leading to data theft, session hijacking, or defacement. Such vulnerabilities are frequently used in mass-exploit campaigns targeting thousands of WordPress sites regardless of popularity [1].

Mitigation

Status

The vendor has not released a patched version for this vulnerability, as the affected version (1.0) appears to be the final release [1]. Immediate action recommended by the advisory is to update the plugin if a newer version becomes available, or to contact the hosting provider or a web developer for assistance [1]. Users may also consider removing or deactivating the plugin until a fix is confirmed.
