CVE-2026-45043

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, improper validation in the PUT /rustfs/admin/v3/import-iam endpoint allows a user with ImportIAMAction to create service accounts under arbitrary parent identities, including the root user (minioadmin). The endpoint accepts attacker-controlled parent, claims, accessKey, and secretKey values without enforcing privilege boundaries or sanitization. This enables privilege escalation to full administrative access using a persistent, attacker-defined credential. This vulnerability is fixed in 1.0.0-beta.2.

Summary		(es) RustFS es un sistema de almacenamiento de objetos distribuido construido en Rust. Antes de 1.0.0-beta.2, una validación incorrecta en el endpoint PUT /rustfs/admin/v3/import-iam permite a un usuario con ImportIAMAction crear cuentas de servicio bajo identidades padre arbitrarias, incluyendo el usuario raíz (minioadmin). El endpoint acepta valores de parent, claims, accessKey y secretKey controlados por el atacante sin aplicar límites de privilegios o sanitización. Esto permite la escalada de privilegios a acceso administrativo completo usando una credencial persistente y definida por el atacante. Esta vulnerabilidad está corregida en 1.0.0-beta.2.
