CVE-2025-54679: Neon Channel Customizer Auth Bypass Flaw

CVE-2025-54679 is an authorization bypass flaw in vertim Neon Channel Product Customizer Free that enables attackers to exploit misconfigured access controls. This article covers technical details, affected versions, and mitigation.

Published: April 22, 2026

CVE-2025-54679 Overview

CVE-2025-54679 is a Missing Authorization vulnerability (CWE-862) affecting the Neon Channel Product Customizer Free WordPress plugin developed by vertim. This security flaw allows attackers to exploit incorrectly configured access control security levels, potentially leading to arbitrary content deletion on vulnerable WordPress installations.

The vulnerability stems from the plugin's failure to properly verify user authorization before performing sensitive operations. Without adequate permission checks, unauthorized users may be able to delete content without proper credentials, compromising the integrity of WordPress sites using this plugin.

Critical Impact

Unauthorized users can exploit missing authorization checks to delete arbitrary content on affected WordPress installations, potentially causing significant data loss and site disruption.

Affected Products

  • Neon Channel Product Customizer Free plugin version 2.0 and earlier
  • WordPress installations with the neon-channel-product-customizer-free plugin installed
  • WordPress sites using product customization functionality through this plugin

Discovery Timeline

  • 2025-08-14 - CVE-2025-54679 published to NVD
  • 2026-04-15 - Last updated in NVD database

Technical Details for CVE-2025-54679

Vulnerability Analysis

This vulnerability is classified under CWE-862 (Missing Authorization), which occurs when a software component does not perform an authorization check when an actor attempts to access a resource or perform an action. In the context of the Neon Channel Product Customizer Free plugin, the missing authorization allows attackers to bypass access control mechanisms and perform unauthorized content deletion.

The flaw enables attackers to exploit incorrectly configured access control security levels within the plugin. Since WordPress plugins often handle AJAX requests and direct actions, a missing capability check on delete operations creates a significant security gap that malicious actors can leverage to remove content from the database.

Root Cause

The root cause of CVE-2025-54679 is the absence of proper authorization verification in the plugin's content deletion functionality. WordPress plugins are expected to implement capability checks using functions like current_user_can() before executing privileged operations. The Neon Channel Product Customizer Free plugin fails to implement these essential security checks, allowing any user—including unauthenticated visitors in some configurations—to trigger deletion actions.

This type of vulnerability typically arises when developers focus on functionality without implementing the principle of least privilege or when AJAX handlers are registered without proper permission callbacks.

Attack Vector

An attacker can exploit this vulnerability by sending crafted requests to the vulnerable plugin endpoints without proper authentication or authorization. The attack typically involves:

  1. Identifying the vulnerable AJAX action or endpoint within the plugin
  2. Crafting malicious requests that target the content deletion functionality
  3. Sending these requests without valid authorization credentials
  4. Successfully deleting arbitrary content due to the missing authorization checks

Since no exploit code has been verified for this vulnerability, technical details regarding the specific exploitation mechanism can be found in the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-54679

Indicators of Compromise

  • Unexpected content deletion in WordPress posts, pages, or custom post types
  • Unusual AJAX requests to plugin-specific endpoints from unauthorized sources
  • Suspicious HTTP POST requests targeting admin-ajax.php with plugin-related actions
  • Anomalous patterns in WordPress audit logs showing content modifications without corresponding admin activity

Detection Strategies

  • Monitor WordPress audit logs for unauthorized content deletion events
  • Implement web application firewall (WAF) rules to detect suspicious requests to the plugin endpoints
  • Deploy file integrity monitoring to detect unexpected changes to plugin files
  • Review server access logs for unusual patterns of requests to admin-ajax.php
  • Utilize SentinelOne Singularity to detect and alert on suspicious WordPress process behaviors

Monitoring Recommendations

  • Enable comprehensive logging for WordPress administrative actions
  • Configure alerts for bulk content deletion events
  • Monitor network traffic for unusual patterns of requests to vulnerable endpoints
  • Implement real-time database monitoring for unexpected DELETE operations
  • Set up SentinelOne policies to monitor WordPress-related process activities and file system changes

How to Mitigate CVE-2025-54679

Immediate Actions Required

  • Immediately disable or remove the Neon Channel Product Customizer Free plugin if running version 2.0 or earlier
  • Audit WordPress content for any unauthorized deletions or modifications
  • Review and backup WordPress database before taking remediation actions
  • Implement additional access controls at the web server level to restrict plugin endpoint access
  • Monitor for any signs of exploitation while awaiting a security patch

Patch Information

At the time of publication, the vulnerability affects Neon Channel Product Customizer Free versions through 2.0. Site administrators should check for available updates from the plugin developer and apply any security patches as soon as they become available. Refer to the Patchstack Vulnerability Report for the latest patch information.

Workarounds

  • Deactivate the Neon Channel Product Customizer Free plugin until a patched version is available
  • Implement web application firewall rules to block unauthorized requests to plugin endpoints
  • Restrict access to admin-ajax.php for unauthenticated users where feasible
  • Use WordPress security plugins to add additional authorization layers
  • Consider switching to an alternative product customizer plugin with proper authorization controls
bash
# WordPress CLI command to deactivate the vulnerable plugin
wp plugin deactivate neon-channel-product-customizer-free

# Verify plugin is deactivated
wp plugin list --status=inactive | grep neon-channel

# Check for available plugin updates
wp plugin update --all --dry-run
