Deeper analysis
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.
