Security readout for executives and security teams
Plain-English summary
CVE-2026-3546 affects the WordPress e-shot form builder plugin through version 1.0.2. A logged-in low-privilege user could access an API token and subaccount information because an AJAX function lacks authorization and nonce checks. This could expose the organization’s e-shot account. Public sources do not name a fixed version or active exploitation.
Executive priority
Treat as a near-term remediation item for sites with user registration or many low-privilege accounts. Prioritize token rotation and plugin update guidance where the e-shot account supports marketing or customer communications.
Technical view
The vulnerable eshot_form_builder_get_account_data() AJAX handler is registered for authenticated users and returns data from the eshotformbuilder_control table. Sources state it lacks a capability check and nonce verification, allowing Subscriber-level users or higher to retrieve the e-shot API token and subaccount data. Classified as CWE-202 sensitive information exposure, CVSS 3.1 score 5.3.
Likely exposure
WordPress sites using e-shot form builder versions up to and including 1.0.2 are potentially exposed, especially if untrusted users can create or hold Subscriber-level accounts.
Exploitation context
Sources describe a low-complexity authenticated information exposure. No CISA KEV listing or cited source confirms active exploitation. The main risk is credential exposure leading to unauthorized access to the victim’s e-shot platform account.
Researcher notes
The source bundle has an inconsistency: the narrative requires authenticated Subscriber-level access, while the CVSS vector lists PR:N. The WordPress wp_ajax context supports authenticated access. No fixed version is identified in the supplied sources.
Mitigation direction
- Check vendor and WordPress plugin guidance for an updated fixed release.
- Disable or remove the plugin if it is not business-critical.
- Limit WordPress account creation and remove unnecessary Subscriber-level users.
- Rotate the e-shot API token if exposure is suspected.
- Review e-shot account activity for unauthorized access or changes.
Validation and detection
- Inventory WordPress sites for e-shot form builder installed versions.
- Flag versions up to and including 1.0.2 for remediation review.
- Confirm low-privilege users cannot access e-shot account data after remediation.
- Review plugin code or vendor notes for capability and nonce checks.
- Check logs for unusual authenticated access to plugin AJAX actions.

Exposure of Sensitive Information Through Data Queries
Exposure of Sensitive Information Through Data Queries represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
