CVE-2025-0692 in Simple Video Management System Plugin
Summary
by MITRE • 02/13/2025
The Simple Video Management System WordPress plugin through 1.0.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

The Simple Video Management System WordPress plugin version 1.0.4 contains a critical stored cross-site scripting vulnerability that arises from inadequate input sanitization and output escaping mechanisms within its administrative settings. This flaw specifically affects high-privilege users such as administrators who possess the capability to modify plugin configurations. The vulnerability exists in the plugin's handling of user-supplied data within its settings interface, where malicious scripts can be injected and subsequently executed when the affected settings are rendered in the administrative dashboard.
The technical nature of this vulnerability stems from the plugin's failure to properly sanitize user input before storing it in the database and subsequently output it without adequate escaping. This creates a persistent XSS vector where an attacker with administrative privileges can inject malicious JavaScript code through the plugin's settings forms. Even in environments where the unfiltered_html capability is restricted - such as multisite WordPress installations where only super administrators can use unfiltered HTML - this vulnerability remains exploitable because the plugin does not implement proper sanitization routines for its configuration parameters.
From an operational perspective, this vulnerability represents a significant risk to WordPress installations using the Simple Video Management System plugin. The stored nature of the XSS means that malicious scripts persist in the database and will execute whenever the affected administrative pages are accessed by any user with appropriate privileges. The impact extends beyond simple script execution as it can enable session hijacking, credential theft, and potentially full system compromise if attackers can leverage the administrative access to manipulate other plugin settings or user accounts. The vulnerability's exploitation requires only administrative privileges, making it particularly dangerous in environments where multiple administrators have access to the system.
Security practitioners should note that this vulnerability aligns with CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') and follows ATT&CK technique T1059.001 - Command and Scripting Interpreter: PowerShell for potential post-exploitation activities. The vulnerability demonstrates poor input validation practices and highlights the importance of implementing comprehensive sanitization routines for all user-supplied data within web applications. Organizations using this plugin should immediately update to the latest version or implement temporary workarounds such as restricting administrative access to the plugin settings or disabling the plugin entirely until a patch is applied.
The security implications of this vulnerability extend to the broader WordPress ecosystem, as it demonstrates how plugin developers often overlook critical security considerations in their configuration interfaces. This flaw represents a common pattern in WordPress plugin development where administrative interfaces receive insufficient input validation and output escaping, creating persistent security risks that can be exploited by attackers who gain administrative access to the system. The vulnerability's presence in a video management plugin specifically highlights the need for security reviews of all plugin components, particularly those that handle user input in administrative contexts. Organizations should implement regular security audits of their WordPress plugin ecosystem to identify similar vulnerabilities and ensure that all plugins maintain proper input sanitization and output escaping mechanisms to prevent stored XSS attacks.
