These vulnerabilities are due to insufficient sanitization of user-supplied data that is stored in the web page. An attacker could exploit these vulnerabilities by convincing a user of the interface to click a specific link or view an affected web page. The injected script code may be executed in the context of the web-based management interface or allow the attacker to access sensitive browser-based information. ## Affected - `identity_services_engine < 3.2.0` - `identity_services_engine = 3.2.0` - `identity_services_engine = 3.3.0` - `identity_services_engine = 3.4.0` ## Remediation Upgrade past the affected range: - `identity_services_engine 3.2.0`
