Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:NSummary
CVE-2026-3546 is a medium-severity Exposure of Sensitive Information Through Data Queries (CWE-202) vulnerability in Wordpress (inferred from references). Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Information Repositories (T1213); ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-23 (Data Mining Protection) — see the control section below for these in your framework.

Vulnerability Data
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.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-23 directly requires mechanisms to protect against unauthorized data mining and inference from statistical queries that would expose sensitive information.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Least-privilege query permissions directly limit the data an attacker can request or infer.
Behavior analytics on query activity can detect inference attempts but does not prevent exposure at query time.
Protecting data-in-use reduces what remains available for inference via queries.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Access control limits who can run queries that could expose sensitive information via inference.
Granular access rights reduce the ability of users to craft inference queries.
Data masking prevents inference by obscuring sensitive values returned in query results.
Information access restriction directly limits query scope that could lead to inference.
Classification helps identify sensitive data that must be protected from inference attacks.
DLP can detect and block queries or result sets that risk exposing sensitive information.
