CVE-2025-14082 identifies an improper access control vulnerability in the Red Hat Build of Keycloak, specifically within the Admin REST API endpoint /admin/realms/{realm}/roles. This endpoint is designed to manage role metadata within a Keycloak realm. The vulnerability arises due to insufficient authorization checks, allowing users with high privileges to retrieve sensitive role metadata that should otherwise be restricted. The flaw does not permit modification or deletion of data, nor does it affect system availability, but it exposes potentially sensitive information about role configurations that could aid an attacker in further privilege escalation or reconnaissance. The vulnerability requires the attacker to have network access and authenticated high-privilege credentials, meaning it cannot be exploited by unauthenticated or low-privilege users. No user interaction is required for exploitation. The CVSS v3.1 score is 2.7, reflecting the limited confidentiality impact and the requirement for high privileges. There are currently no known exploits in the wild, and no official patches or mitigations have been published by Red Hat at the time of disclosure. This vulnerability highlights the importance of rigorous authorization checks in administrative APIs managing identity and access management systems like Keycloak.

For European organizations, the impact of CVE-2025-14082 is primarily related to confidentiality. Exposure of sensitive role metadata could enable an attacker with high privileges to better understand the access control structure, potentially facilitating further attacks such as privilege escalation or lateral movement within the network. While the vulnerability does not directly compromise data integrity or availability, the leaked information could be leveraged in targeted attacks against critical systems. Organizations relying on Keycloak for identity and access management, especially those in regulated sectors like finance, healthcare, or government, may face increased risk if attackers gain insights into role assignments and permissions. The requirement for high-privilege authentication limits the scope of impact, but insider threats or compromised privileged accounts could exploit this vulnerability. Given the widespread use of Red Hat and Keycloak in European enterprises and public sector institutions, the vulnerability warrants attention to prevent information leakage that could aid adversaries.

To mitigate CVE-2025-14082, European organizations should implement the following specific measures: 1) Enforce the principle of least privilege rigorously, ensuring that only necessary users have high-level administrative access to Keycloak. 2) Conduct thorough audits of all accounts with elevated privileges and monitor their API usage patterns for anomalies. 3) Restrict network access to the Keycloak Admin REST API endpoints to trusted management networks or VPNs to reduce exposure. 4) Implement strong authentication mechanisms such as multi-factor authentication (MFA) for all administrative users to reduce the risk of credential compromise. 5) Regularly review and update Keycloak configurations to ensure that authorization policies are correctly enforced and that no overly permissive roles exist. 6) Stay informed about Red Hat security advisories and apply patches or updates promptly once available. 7) Consider deploying Web Application Firewalls (WAFs) or API gateways with fine-grained access controls and logging to detect and block unauthorized API calls. 8) Incorporate this vulnerability into incident response plans to quickly address any suspicious activity related to role metadata access.
