Hashgraph Guardian versions up to 3.6.0 contain a stored cross-site scripting (XSS) vulnerability. Authenticated users with the STANDARD_REGISTRY role can inject malicious JavaScript via the companyName field in the branding configuration API. This vulnerability arises from improper input neutralization in the branding service's innerHTML assignment, allowing script execution in the browsers of authenticated users on every page load. The issue was fixed in a commit identified as ba8c566.

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.

A Stored HTML Injection vulnerability was discovered in the Users functionality due to improper validation of an input parameter. An authenticated user with administrative privileges can create a malicious user whose username contains HTML tags. When a victim attempts to delete a group containing the affected user, 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.
