CVE-2026-25320: Elementor Contact Form DB Auth Bypass

CVE-2026-25320 Overview

CVE-2026-25320 is a Missing Authorization vulnerability affecting the Elementor Contact Form DB WordPress plugin (sb-elementor-contact-form-db) developed by Cool Plugins. This vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to sensitive form submission data stored by the plugin. The vulnerability stems from broken access control mechanisms that fail to properly verify user permissions before granting access to protected functionality.

Critical Impact

Unauthorized users may be able to access, modify, or delete contact form submissions stored by the Elementor Contact Form DB plugin, potentially exposing sensitive user data submitted through website forms.

Affected Products

• Elementor Contact Form DB (sb-elementor-contact-form-db) versions through 2.1.3
• WordPress installations using the vulnerable plugin versions
• Websites using Elementor page builder with the Contact Form DB addon

Technical Details for CVE-2026-25320

Vulnerability Analysis

This vulnerability is classified under CWE-862 (Missing Authorization), which occurs when a web application does not perform authorization checks to ensure that a user has sufficient privileges before accessing protected resources or functionality. In the context of the Elementor Contact Form DB plugin, the vulnerability allows attackers to bypass access control mechanisms that should restrict access to form submission data and administrative functions.

The attack can be executed remotely over the network without requiring authentication, making it accessible to any attacker who can reach the vulnerable WordPress installation. The vulnerability primarily affects data integrity, allowing unauthorized modification of information without impacting confidentiality or availability directly.

Root Cause

The root cause of this vulnerability is the absence of proper authorization checks in the plugin's access control implementation. The Elementor Contact Form DB plugin fails to verify whether a user has the necessary permissions before allowing access to protected endpoints or functionality. This typically manifests when plugin developers omit capability checks (such as current_user_can() in WordPress) or implement them incorrectly, allowing unauthenticated or low-privileged users to perform actions that should be restricted to administrators.

Attack Vector

The vulnerability can be exploited through the network (AV:N) with low attack complexity (AC:L), requiring no privileges (PR:N) or user interaction (UI:N). An attacker can craft malicious requests to the vulnerable WordPress site targeting the plugin's unprotected endpoints. Since no authentication is required, attackers can potentially access or manipulate contact form submissions by directly interacting with the plugin's functionality without proper authorization checks blocking their requests.

The attack typically involves identifying the vulnerable plugin endpoints and sending crafted HTTP requests that bypass the missing authorization controls. For detailed technical information on the vulnerability mechanism, refer to the Patchstack Vulnerability Advisory.

Detection Methods for CVE-2026-25320

Indicators of Compromise

• Unusual access patterns to WordPress admin endpoints related to form submissions
• Unexpected modifications to contact form database entries
• Anomalous HTTP requests targeting the sb-elementor-contact-form-db plugin endpoints
• Access logs showing unauthenticated requests to plugin administrative functions

Detection Strategies

• Monitor WordPress access logs for suspicious requests to the Elementor Contact Form DB plugin endpoints
• Implement web application firewall (WAF) rules to detect unauthorized access attempts to plugin functionality
• Review audit logs for unexpected changes to form submission data
• Deploy intrusion detection systems (IDS) to identify patterns consistent with access control bypass attempts

Monitoring Recommendations

• Enable detailed logging for all WordPress plugin activities
• Configure alerts for failed authorization attempts and unusual access patterns
• Regularly audit user access permissions and plugin settings
• Monitor for unexpected changes to plugin files or database tables associated with form submissions

How to Mitigate CVE-2026-25320

Immediate Actions Required

• Update the Elementor Contact Form DB plugin to a patched version when available
• Review all form submission data for signs of unauthorized access or modification
• Temporarily disable the plugin if no patch is available and risk is unacceptable
• Implement additional access controls at the server or WAF level to restrict plugin access

Patch Information

A security patch addressing this vulnerability should be obtained from the plugin developer or WordPress plugin repository. Users should update to a version newer than 2.1.3 when available. For the latest information on patches and updates, consult the Patchstack Vulnerability Advisory.

Workarounds

• Restrict access to WordPress admin areas using IP whitelisting at the server level
• Implement a web application firewall (WAF) to filter malicious requests targeting the plugin
• Disable the plugin temporarily until a security patch is available
• Apply WordPress security hardening best practices to minimize exposure

# Configuration example - Restrict access to plugin endpoints via .htaccess
<FilesMatch "sb-elementor-contact-form-db">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</FilesMatch>
