Stored XSS via unescaped notification templates
Published Mar 19, 2026 · Updated Mar 19, 2026
Stored XSS in FreeScout before 1.8.209 allows remote attackers to inject HTML into notification emails by sending a crafted message. Incoming email bodies are stored without sanitization, and two Blade notification templates render the stored thread body as raw HTML instead of using getCleanBody(). Agents or administrators must open a generated notification; HTML injection affects all clients, while script execution depends on the recipient email client.
