      "value": "JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to v3.10.21-lts and v4.10.12-lts, a low-privileged authenticated user can invoke LDAP configuration tests and start LDAP synchronization by sending crafted messages to the /ws/ldap/ WebSocket endpoint, bypassing authorization checks and potentially exposing LDAP credentials or causing unintended sync operations. This vulnerability is fixed in v3.10.21-lts and v4.10.12-lts."

Antes de las versiones v3.10.21-lts y v4.10.12-lts, un usuario autenticado con bajos privilegios puede invocar pruebas de configuración LDAP e iniciar la sincronización LDAP enviando mensajes manipulados al endpoint WebSocket /ws/ldap/, eludiendo las comprobaciones de autorización y potencialmente exponiendo credenciales LDAP o causando operaciones de sincronización no intencionadas. Esta vulnerabilidad está corregida en las versiones v3.10.21-lts y v4.10.12-lts."
