CVE-2023-4918: Red Hat Keycloak

High severity, CVSS 8.8. EPSS: 0.6% chance of exploitation in the next 30 days.

A flaw was found in the Keycloak package, more specifically org.keycloak.userprofile. When a user registers itself through registration flow, the "password" and "password-confirm" field from the form will occur as regular user attributes. All users and clients with proper rights and roles are able to read users attributes, allowing a malicious user with minimal access to retrieve the users passwords in clear text, jeopardizing their environment.

Affected products

• Red Hat Keycloak: version 22.0.2 only
