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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":6.8},"cwes":["CWE-1327"],"references":["https://access.redhat.com/errata/RHSA-2025:21370","https://access.redhat.com/errata/RHSA-2025:21371","https://access.redhat.com/security/cve/CVE-2025-11538","https://bugzilla.redhat.com/show_bug.cgi?id=2402622","https://github.com/keycloak/keycloak/commit/9e98f2bf961f68853cea6fbec58b512ed8be7ca9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-11538","score":0.00425,"percentile":0.36448,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j4vq-q93m-4683","url":"https://osv.dev/vulnerability/GHSA-j4vq-q93m-4683","summary":"Keycloak has debug default bind address","modified":"2025-12-02T01:29:45.510324Z","packages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-quarkus-dist","purl":"pkg:maven/org.keycloak/keycloak-quarkus-dist","ranges":["<26.4.4"],"fixed":["26.4.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
