Description

A Stored HTML Injection vulnerability was discovered in the Smart Polling functionality due to improper validation of an input parameter. An authenticated user with limited privileges can push malicious remote strategies containing HTML tags through the sync. When a victim views the affected remote strategy in the Smart Polling functionality, the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.
