Title
Arcane before 2.0.0 Missing Administrator Authorization on the Compose Template Mutation Endpoints
Summary
Arcane versions before 2.0.0 fail to properly restrict template operations, allowing default user role accounts to create, modify, and delete compose templates including instance-wide defaults. Attackers can inject malicious container configurations with privileged settings or host path mounts that execute with administrative privileges when deployed by administrators.
