CVE-2026-24602: Raptive Ads Authorization Bypass Vulnerability

CVE-2026-24602 Overview

CVE-2026-24602 is a Missing Authorization vulnerability (CWE-862) affecting the Raptive Ads WordPress plugin (adthrive-ads). This broken access control flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to plugin functionality without proper authentication checks.

Critical Impact

Unauthenticated attackers can bypass authorization controls to access restricted plugin functionality, potentially exposing sensitive configuration data or ad-related information.

Affected Products

• Raptive Ads WordPress Plugin versions up to and including 3.10.0
• WordPress sites running vulnerable versions of the adthrive-ads plugin

Technical Details for CVE-2026-24602

Vulnerability Analysis

This vulnerability stems from a missing authorization check in the Raptive Ads WordPress plugin. The flaw allows unauthenticated users to access functionality that should be restricted to authenticated administrators or authorized users. Without proper capability checks or nonce verification on sensitive AJAX endpoints or plugin functions, attackers can interact with the plugin in ways that were not intended by the developers.

The vulnerability is classified under CWE-862 (Missing Authorization), which occurs when software does not perform authorization checks when an actor attempts to access a resource or perform an action. In the context of WordPress plugins, this typically manifests as missing current_user_can() checks or absent nonce verification on AJAX handlers and REST API endpoints.

Root Cause

The root cause is the absence of proper authorization verification before executing sensitive plugin operations. WordPress plugins must implement capability checks using functions like current_user_can() combined with nonce verification via wp_verify_nonce() to ensure that only authorized users can perform restricted actions. The Raptive Ads plugin failed to implement these security controls on one or more endpoints, creating a broken access control condition.

Attack Vector

The attack can be executed remotely over the network without any authentication requirements. An attacker can craft HTTP requests directly to vulnerable AJAX endpoints or plugin functions that lack proper authorization checks. The attack requires no user interaction and can be performed with low complexity.

The exploitation scenario typically involves:

1. Identifying AJAX action hooks or REST endpoints exposed by the plugin
2. Crafting malicious requests to these endpoints without authentication
3. Accessing or modifying data that should require administrator privileges

Detection Methods for CVE-2026-24602

Indicators of Compromise

• Unusual AJAX requests to admin-ajax.php with Raptive Ads-related action parameters from unauthenticated sessions
• Unexpected access patterns to plugin-specific endpoints without corresponding WordPress authentication cookies
• Log entries showing access to ad configuration or settings endpoints from external IP addresses
• Anomalous modification timestamps on plugin settings or configuration files

Detection Strategies

• Monitor WordPress access logs for requests to admin-ajax.php containing adthrive or raptive action parameters from unauthenticated users
• Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting known vulnerable endpoints
• Deploy file integrity monitoring on WordPress plugin directories to detect unauthorized configuration changes
• Use security plugins that log and alert on unauthorized access attempts to plugin functionality

Monitoring Recommendations

• Enable verbose logging for WordPress AJAX requests and REST API endpoints
• Configure alerts for repeated unauthorized access attempts to plugin-specific functionality
• Regularly audit WordPress user access logs for anomalies
• Monitor network traffic for patterns consistent with automated vulnerability scanning targeting WordPress plugins

How to Mitigate CVE-2026-24602

Immediate Actions Required

• Update the Raptive Ads plugin to a version newer than 3.10.0 that includes the security patch
• Conduct a security audit of your WordPress installation to identify any signs of exploitation
• Review WordPress access logs for suspicious activity targeting the vulnerable plugin
• Consider temporarily deactivating the plugin if an update is not immediately available

Patch Information

The vulnerability affects Raptive Ads plugin versions through 3.10.0. Website administrators should update to the latest available version that addresses this broken access control issue. Check the WordPress plugin repository or the Patchstack advisory for patch availability information.

Workarounds

• Temporarily deactivate the Raptive Ads plugin until a patched version is available
• Implement WAF rules to block unauthorized requests to vulnerable plugin endpoints
• Restrict access to admin-ajax.php for sensitive actions using server-level access controls
• Use a WordPress security plugin to add additional authorization layers to AJAX handlers

# Apache .htaccess configuration to restrict AJAX access (temporary mitigation)
# Add to WordPress root .htaccess file
<Files admin-ajax.php>
    # Allow legitimate admin requests
    <RequireAny>
        Require ip 127.0.0.1
        Require ip ::1
        # Add trusted IP addresses as needed
    </RequireAny>
</Files>
