{"id":"GHSA-j4vq-q93m-4683","summary":"Keycloak has debug default bind address","details":"A vulnerability exists in Keycloak's server distribution where enabling debug mode (`--debug`) insecurely defaults to binding the Java Debug Wire Protocol (JDWP) port to all network interfaces (`0.0.0.0`). This exposes the debug port to the local network, allowing an attacker on the same network segment to attach a remote debugger and achieve remote code execution within the Keycloak Java virtual machine.\n\nRed Hat evaluates this as a Moderate impact vulnerability due to the requirement of running debug mode and untrusted network. Also, for Red Hat Single Sign-On, this must as well be bound to 0.0.0.0 address, which is not recommended in production scenarios.","aliases":["CVE-2025-11538"],"modified":"2025-12-02T01:29:45.510324Z","published":"2025-12-02T00:35:03Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2025-12-02T00:35:03Z","nvd_published_at":null,"cwe_ids":["CWE-1327"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/keycloak/keycloak/security/advisories/GHSA-j4vq-q93m-4683"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-11538"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2025:21370"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2025:21371"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2025-11538"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2402622"},{"type":"PACKAGE","url":"https://github.com/keycloak/keycloak"}],"affected":[{"package":{"name":"org.keycloak:keycloak-quarkus-dist","ecosystem":"Maven","purl":"pkg:maven/org.keycloak/keycloak-quarkus-dist"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.4.4"}]}],"versions":["17.0.0","17.0.1","18.0.0","18.0.1","18.0.2","19.0.0","19.0.1","19.0.2","19.0.3","20.0.0","20.0.1","20.0.2","20.0.3","20.0.5","21.0.0","21.0.1","21.0.2","21.1.0","21.1.1","21.1.2","22.0.0","22.0.1","22.0.2","22.0.3","22.0.4","22.0.5","23.0.0","23.0.1","23.0.2","23.0.3","23.0.4","23.0.5","23.0.6","23.0.7","24.0.0","24.0.1","24.0.2","24.0.3","24.0.4","24.0.5","25.0.0","25.0.1","25.0.2","25.0.3","25.0.4","25.0.5","25.0.6","26.0.0","26.0.1","26.0.2","26.0.4","26.0.5","26.0.6","26.0.7","26.0.8","26.1.0","26.1.1","26.1.2","26.1.3","26.1.4","26.1.5","26.2.0","26.2.1","26.2.2","26.2.3","26.2.4","26.2.5","26.3.0","26.3.1","26.3.2","26.3.3","26.3.4","26.3.5","26.4.0","26.4.1","26.4.2","26.4.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/12/GHSA-j4vq-q93m-4683/GHSA-j4vq-q93m-4683.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
