Published Jul 11, 2026 · Updated Jul 11, 2026

Stored XSS in Print, PDF & Email by PrintFriendly 5.5.10 and earlier allows remote authenticated users to inject scripts through plugin CSS. The plugin stores content_position_css without sufficient sanitization and later emits it into page output without context-appropriate escaping. Administrator-level access is required to save the setting; injected scripts execute when a visitor accesses an affected page.
