Overview

CVE-2026-3546 is a medium-severity vulnerability. It was published on March 21, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The e-shot form builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.0.2. The eshot_form_builder_get_account_data() function is registered as a wp_ajax_ AJAX handler accessible to all authenticated users. The function lacks any capability check (e.g., current_user_can('manage_options')) and does not verify a nonce. It directly queries the database for the e-shot API token stored in the eshotformbuilder_control table and returns it along with all subaccount data as a JSON response. This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract the e-shot API token and subaccount information, which could then be used to access the victim's e-shot platform account.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
