CVE-2025-48255: Videowhisper Live Streaming CSRF Vulnerability

CVE-2025-48255 Overview

CVE-2025-48255 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the VideoWhisper Broadcast Live Video plugin for WordPress. This plugin, also known as videowhisper-live-streaming-integration, provides live streaming capabilities including WebRTC, HLS, RTSP, and RTMP support. The vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users by tricking them into visiting malicious web pages or clicking crafted links.

Critical Impact

Attackers can exploit this CSRF vulnerability to perform administrative actions without authorization, potentially compromising site integrity, user data, and live streaming configurations.

Affected Products

• VideoWhisper Broadcast Live Video (videowhisper-live-streaming-integration) versions through 6.2.4
• WordPress installations using the vulnerable plugin versions
• Sites utilizing WebRTC, HLS, RTSP, or RTMP streaming features through this plugin

Technical Details for CVE-2025-48255

Vulnerability Analysis

This CSRF vulnerability exists due to insufficient validation of request origins in the VideoWhisper Broadcast Live Video WordPress plugin. The plugin fails to implement proper nonce verification or other anti-CSRF tokens for sensitive operations, allowing attackers to craft malicious requests that execute when authenticated administrators or users visit attacker-controlled pages.

The vulnerability enables attackers to perform actions within the WordPress administrative context, including modifying plugin settings, altering streaming configurations, or potentially escalating to more severe attacks depending on the plugin's functionality and the victim's privilege level.

Root Cause

The root cause is the absence or improper implementation of CSRF protection mechanisms within the plugin's form handlers and AJAX endpoints. WordPress provides built-in nonce functions (wp_nonce_field(), wp_verify_nonce(), check_admin_referer()) specifically designed to prevent CSRF attacks, but the vulnerable versions of this plugin do not adequately utilize these protections for critical operations.

Attack Vector

The attack is network-based and requires user interaction. An attacker must craft a malicious HTML page containing hidden forms or JavaScript that automatically submits requests to the vulnerable WordPress endpoints. When an authenticated user visits this malicious page, the browser automatically includes their session cookies, causing the forged request to be processed as if it were legitimate.

The attack flow typically involves:

1. Attacker identifies unprotected administrative actions in the plugin
2. Attacker crafts a malicious page with hidden form submissions targeting vulnerable endpoints
3. Attacker lures an authenticated WordPress administrator to visit the malicious page
4. The victim's browser automatically submits the forged request with valid session credentials
5. The WordPress site processes the request, executing the attacker's intended action

Detection Methods for CVE-2025-48255

Indicators of Compromise

• Unexpected changes to VideoWhisper plugin settings without administrator action
• Unusual HTTP POST requests to plugin endpoints originating from external referrers
• Modified streaming configurations or channel settings without corresponding admin activity logs
• Suspicious outbound traffic patterns from WordPress admin sessions

Detection Strategies

• Monitor WordPress access logs for requests to videowhisper-live-streaming-integration endpoints with external or missing Referer headers
• Implement Web Application Firewall (WAF) rules to detect and block requests lacking valid nonces
• Review WordPress audit logs for configuration changes that don't correlate with legitimate admin sessions
• Deploy SentinelOne Singularity XDR to detect anomalous web application behavior and CSRF attack patterns

Monitoring Recommendations

• Enable comprehensive logging for all WordPress administrative actions
• Configure alerts for plugin setting modifications occurring outside normal business hours
• Monitor for patterns of rapid sequential requests that may indicate automated CSRF exploitation
• Implement referrer validation at the web server level as an additional defense layer

How to Mitigate CVE-2025-48255

Immediate Actions Required

• Update the VideoWhisper Broadcast Live Video plugin to a patched version when available from the vendor
• Consider temporarily disabling the plugin if it is not critical to operations until a patch is released
• Implement additional CSRF protections at the web server or WAF level
• Educate administrators about the risks of clicking untrusted links while logged into WordPress

Patch Information

At the time of publication, administrators should monitor the Patchstack vulnerability database for updates regarding patches from VideoWhisper. Ensure automatic updates are enabled for WordPress plugins or manually check for updates regularly.

Workarounds

• Restrict administrative access to the WordPress dashboard from trusted IP addresses only
• Use a Web Application Firewall (WAF) with CSRF protection rules enabled
• Implement the WordPress security plugin with additional CSRF protections
• Advise administrators to use separate browser profiles or incognito mode when visiting untrusted websites while managing WordPress

# Apache .htaccess configuration to restrict admin access by IP

    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
