Technical Details for CVE-2026-28131

Vulnerability Analysis

This vulnerability is classified under CWE-201 (Insertion of Sensitive Information Into Sent Data), which occurs when an application unintentionally includes sensitive information within data that is transmitted to external parties. In the context of the Elementor Addon Elements plugin, this manifests as improper handling of sensitive data during normal plugin operations.

The vulnerability affects all versions of the Elementor Addon Elements plugin from the initial release through version 1.14.4. When exploited, attackers can retrieve embedded sensitive data that should not be accessible to unauthorized users. This type of information disclosure can lead to further attacks on the WordPress installation or compromise of user data.

Root Cause

The root cause of this vulnerability lies in the plugin's data handling mechanisms where sensitive information is improperly included in data transmissions. The Elementor Addon Elements plugin fails to adequately sanitize or filter sensitive information before including it in responses or data payloads sent to users.

This type of vulnerability typically occurs when:

• Debug information is inadvertently left in production code
• Internal data structures are exposed through API responses
• Sensitive configuration details are embedded in page elements
• User data is improperly included in rendered content

Attack Vector

The attack vector for CVE-2026-28131 involves retrieving embedded sensitive data from affected WordPress installations. An attacker could potentially:

1. Access the WordPress site running the vulnerable plugin
2. Interact with functionality provided by the Elementor Addon Elements plugin
3. Analyze responses and rendered content to identify exposed sensitive data
4. Extract confidential information from the improperly handled data

The vulnerability requires network access to the target WordPress site but may not require authentication depending on how the sensitive data is exposed. For detailed technical information, see the Patchstack WordPress Vulnerability Report.
