CVE-2026-44825
Apache Solr: Enabling BasicAuth using bin/solr CLI configures additional insecure users
Description
Hardcoded credentials in the Basic Authentication setup tool (bin/solr auth enable) in Apache Solr versions 9.4.0 through 9.10.1 and 10.0.0 allows a remote attacker to gain full administrative access to the cluster via publicly known default credentials installed silently alongside the user-specified account. As an immediate workaround without upgrading, delete the template users (superadmin, admin, search, index) from security.json or change their passwords. The future, not yet released, versions 9.11.0 and 10.1.0 will not be vulnerable, and it will be enough to upgrade to solve the issue. Not affected: * Clusters where bin/solr auth enable was not used to bootstrap BasicAuth * Clusters where template users have been assigned strong passwords after bootstrap

Action Type Old Value New Value Added Translation Title: Apache Solr de Apache Software Foundation, Description: Credenciales codificadas en la herramienta de configuración de Autenticación Básica (bin/solr auth enable) en las versiones de Apache Solr 9.4.0 a 9.10.1 y 10.0.0 permiten a un atacante remoto obtener acceso administrativo completo al clúster a través de credenciales predeterminadas conocidas públicamente instaladas silenciosamente junto con la cuenta especificada por el usuario. Como una solución alternativa inmediata sin actualizar, elimine los usuarios de plantilla (superadmin, admin, search, index) de security.json o cambie sus contraseñas. Las futuras versiones, aún no lanzadas, 9.11.0 y 10.1.0 no serán vulnerables, y será suficiente actualizar para resolver el problema. No afectados: * Clústeres donde no se usó bin/solr auth enable para iniciar BasicAuth * Clústeres donde a los usuarios de plantilla se les han asignado contraseñas seguras después del inicio -
