This behavior allows an attacker to trick the server into making unintended requests to internal or restricted resources. As a result, sensitive internal services such as cloud metadata endpoints could be accessed. This issue may lead to information disclosure and enable attackers to map internal network infrastructure."},{"lang":"es","value":"Se identificó una vulnerabilidad en Keycloak, una solución de gestión de identidades y accesos, donde sigue incorrectamente las redirecciones HTTP al procesar ciertas solicitudes de configuración del cliente. Este comportamiento permite a un atacante engañar al servidor para que realice solicitudes no intencionadas a recursos internos o restringidos. Como resultado, servicios internos sensibles como los puntos finales de metadatos en la nube podrían ser accedidos. Este problema puede llevar a la revelación de información y permitir a los atacantes mapear la infraestructura de red interna."}],"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","baseScore":5.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}]},"weaknesses":[{"source":"secalert@redhat.com","type":"Primary","description":[{"lang":"en","value":"CWE-918"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:build_of_keycloak:-:*:*:*:-:*:*:*","matchCriteriaId":"E5C930CB-4EAD-497B-A44B-D880F2A1F85B"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:jboss_enterprise_application_platform:8.0.0:*:*:*:*:*:*:*","matchCriteriaId":"0D8BC03A-4198-4488-946B-3F6B43962942"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:jboss_enterprise_application_platform_expansion_pack:-:*:*:*:*:*:*:*","matchCriteriaId":"0A24CBFB-4900-47A5-88D2-A44C929603DC"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:single_sign-on:7.0:*:*:*:*:*:*:*","matchCriteriaId":"9EFEC7CA-8DDA-48A6-A7B6-1F1D14792890"}]}]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-4366","source":"secalert@redhat.com","tags":["Vendor Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2448543","source":"secalert@redhat.com","tags":["Issue Tracking","Vendor Advisory"]}]}}]}
