Description

A Stored HTML Injection vulnerability was discovered in the Credentials Manager functionality due to improper validation of an input parameter. An authenticated user with administrative privileges can define a malicious identity containing HTML tags. When a victim attempts to delete the affected identity, 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.
