Description

The Sign-up Sheets WordPress plugin before 1.0.14 did not sanitise or escape some of its fields when creating a new sheet, allowing high privilege users to add JavaScript in them, leading to a Stored Cross-Site Scripting issue. The payloads will be triggered when viewing the 'All Sheets' page in the admin dashboard

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.
