Authenticated stored XSS via unsanitized settings
Published Nov 17, 2021 · Updated Aug 3, 2024
Cross-site scripting in Sprout Invoices before 19.9.7 allows remote authenticated users to inject scripts through plugin settings. The plugin fails to sanitize and escape certain settings before rendering them in WordPress administration pages, allowing a stored payload to execute in an administrator’s browser. Exploitation requires a high-privilege WordPress account and user interaction with the affected page; the demonstrated impact is script execution in that administrative context.
