Description

This security bulletin contains information about 2 vulnerabilities.


1) Command Injection (CVE-ID: CVE-2025-8419)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary SMTP commands.

2) Input validation error (CVE-ID: CVE-2025-9162)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied input within the keycloak-model-storage-service component. The KeycloakRealmImport custom resource substitutes placeholders within imported realm documents, potentially referencing environment variables. A remote privileged user can inject malicious content during the realm import procedure and gain access to sensitive information.
