Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct remote unauthenticated exploitation of public-facing WordPress plugin (T1190) to extract arbitrary post metadata containing sensitive data/credentials (T1005, T1552.001).
NVD Description
The Ninja Forms plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.14.0. This is due to the unsafe application of the `ninja_forms_merge_tags` filter to user-supplied input within repeater fields, which allows the…

resolution of `{post_meta:KEY}` merge tags without authorization checks. This makes it possible for unauthenticated attackers to extract arbitrary post metadata from any post on the site, including sensitive data such as WooCommerce billing emails, API keys, private tokens, and customer personal information via the `nf_ajax_submit` AJAX action.
Deeper analysisAI
CVE-2026-2268 is a sensitive information exposure vulnerability (CWE-200) affecting the Ninja Forms plugin for WordPress in all versions up to and including 3.14.0. The issue stems from the unsafe application of the `ninja_forms_merge_tags` filter to user-supplied input within repeater fields, enabling the unauthorized resolution of `{post_meta:KEY}` merge tags. This flaw, assigned a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), was published on 2026-02-10.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity by submitting crafted data via the `nf_ajax_submit` AJAX action. Successful exploitation allows extraction of arbitrary post metadata from any post on the site, potentially exposing sensitive information such as WooCommerce billing emails, API keys, private tokens, and customer personal data.
References point to specific code locations in the plugin, including Submission.php lines 222 and 706, and WP.php line 48 in version 3.13.3, as well as a patch applied in changeset 3454719 to the trunk. A Wordfence threat intelligence advisory provides further details on the issue.
