Subscriber-level script execution via unsanitized input
Published Jul 20, 2024 · Updated Apr 28, 2026
Stored XSS in Martin Gibson WP GoToWebinar 15.7 and earlier allows remote authenticated users to inject scripts into WordPress pages. The plugin stores attacker-supplied input without sufficient sanitization and renders it without adequate output escaping; public sources do not identify the affected parameter or function. Subscriber-level access is sufficient, and the injected script executes when another user opens an affected page, enabling actions in that user's browser context.
