Description

An issue was discovered in the SiteOrigin Page Builder plugin before 2.10.16 for WordPress. The live editor feature did not do any nonce verification, allowing for requests to be forged on behalf of an administrator. The live_editor_panels_data $_POST variable allows for malicious JavaScript to be executed in the victim's browser.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • n/a n/a — Versions not specified
