CyberRota Analysis
AI-GeneratedA vulnerability exists in the first-broker-login flow of the Keycloak identity management service, where the verification proof for linking social identity provider accounts is not securely bound to the specific upstream identity. This flaw allows an attacker with a different account on the same social provider to hijack the linking process, potentially granting them unauthorized access to the victim's local profile. Organizations using Keycloak for identity management should prioritize addressing this issue to protect user accounts from unauthorized access.
Original NVD Description
A flaw was found in the first-broker-login flow of the Keycloak identity management service. When a user links a social identity provider account to their local account, the verification proof generated is not strictly bound to the specific upstream identity being verified. This allows an attacker with a different account on the same social provider to intercept the process and link their own account to the victim's local profile, gaining unauthorized access.
