Title
Ninja Forms Unauthenticated Stored Cross-Site Scripting via Repeatable Fieldset Submission Index
Summary
Ninja Forms plugin for WordPress versions 3.10.4 through 3.14.9 contains an unauthenticated stored cross-site scripting vulnerability in the Repeatable Fieldset feature where parseSubmissionIndex() accepts arbitrary strings as submission indexes without numeric validation, and admin_form_element() interpolates the index directly into HTML without escaping. An unauthenticated attacker can submit a public form with a crafted repeater child key containing malicious script payloads, which execute in an administrator's browser when viewing submissions in the WordPress admin panel, enabling session-cookie theft, creation of administrator accounts, installation of malicious plugins, and arbitrary modification of site content.
