CVE-2026-24556: ElementCamp Auth Bypass Vulnerability

CVE-2026-24556 Overview

A Missing Authorization vulnerability has been identified in the wpdive ElementCamp WordPress plugin (element-camp). This security flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to restricted functionality or sensitive information within WordPress installations using the affected plugin.

Critical Impact

Unauthenticated attackers can bypass access controls to access restricted plugin functionality without proper authorization, potentially exposing sensitive site data.

Affected Products

• ElementCamp WordPress Plugin versions up to and including 2.3.2
• WordPress installations with ElementCamp plugin active

Technical Details for CVE-2026-24556

Vulnerability Analysis

This vulnerability is classified as CWE-862 (Missing Authorization), a Broken Access Control flaw that occurs when the ElementCamp plugin fails to properly verify user permissions before granting access to certain functionality. The vulnerability is network-exploitable, requiring no authentication or user interaction to trigger, though the impact is limited to unauthorized information disclosure.

The missing authorization check allows any remote attacker to access functionality that should be restricted to authenticated users or administrators. While the confidentiality impact is limited (partial information disclosure), the ease of exploitation makes this a concern for sites using the vulnerable plugin versions.

Root Cause

The root cause of this vulnerability lies in the ElementCamp plugin's failure to implement proper authorization checks on certain endpoints or functions. When processing requests, the plugin does not adequately verify that the requesting user has the appropriate permissions to perform the requested action, allowing unauthorized access to protected resources.

This type of broken access control typically occurs when developers assume that hiding functionality from the user interface is sufficient protection, without implementing server-side authorization verification.

Attack Vector

The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely over the internet. The exploitation requires:

• No prior authentication to the target WordPress site
• No user interaction from site visitors or administrators
• Direct HTTP requests to vulnerable plugin endpoints

An attacker would craft HTTP requests to the vulnerable ElementCamp plugin endpoints, bypassing the intended access control mechanisms to retrieve information that should be restricted. Since no authentication is required, any remote attacker can attempt exploitation against vulnerable installations.

Detection Methods for CVE-2026-24556

Indicators of Compromise

• Unusual HTTP requests to ElementCamp plugin endpoints from unauthenticated sources
• Unexpected access patterns to plugin-specific URLs or AJAX handlers
• Web server logs showing repeated requests to /wp-content/plugins/element-camp/ endpoints from external IPs
• Anomalous data access patterns indicating information enumeration attempts

Detection Strategies

• Monitor WordPress access logs for requests to ElementCamp plugin endpoints from unauthenticated users
• Implement web application firewall (WAF) rules to detect and block suspicious requests targeting plugin functionality
• Use WordPress security plugins to audit access control events and flag unauthorized access attempts
• Review server logs for patterns of enumeration or unauthorized data retrieval

Monitoring Recommendations

• Enable detailed logging for the ElementCamp plugin and WordPress core access events
• Set up alerts for unusual request volumes targeting plugin endpoints
• Monitor for access attempts to administrative or restricted plugin functionality from non-admin sessions
• Conduct periodic security audits of installed plugin versions against known vulnerability databases

How to Mitigate CVE-2026-24556

Immediate Actions Required

• Update the ElementCamp plugin to a patched version newer than 2.3.2 when available
• Review the Patchstack Vulnerability Report for specific remediation guidance
• Audit access logs for any signs of prior exploitation
• Consider temporarily disabling the plugin if no patch is available and the functionality is not critical

Patch Information

Check the WordPress plugin repository and the wpdive vendor website for updates to the ElementCamp plugin that address this missing authorization vulnerability. Monitor the Patchstack advisory for patch availability notifications.

Workarounds

• Implement web application firewall (WAF) rules to restrict access to ElementCamp plugin endpoints to authenticated users only
• Use WordPress security plugins to add additional access control layers to plugin functionality
• Limit access to the WordPress admin area by IP address if possible
• Consider removing or deactivating the ElementCamp plugin until a patched version is released

# Example: Block direct access to ElementCamp plugin directory via .htaccess
# Add to WordPress .htaccess or within /wp-content/plugins/element-camp/.htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    # Block direct PHP file access in plugin directory from unauthenticated users
    RewriteCond %{REQUEST_URI} ^/wp-content/plugins/element-camp/
    RewriteCond %{HTTP_COOKIE} !wordpress_logged_in
    RewriteRule ^(.*)$ - [F,L]
</IfModule>
