Stored script execution via unescaped form-field names

Published Apr 10, 2023 · Updated Feb 11, 2025

Stored XSS in Simple Giveaways before 2.45.1 allows remote authenticated users to inject scripts through giveaway form-field names. The Giveaways > Settings > Forms handler stores an unsanitized Field Name and renders it without output escaping when the settings page is edited. Administrator-level access is required, and the injected script executes in the browser of a user who revisits and edits the affected settings, even where unfiltered_html is disabled.
