NVD Description

Note: Versions mentioned in the description apply only to the upstream seaweedfs-cosi-driver package and not the seaweedfs-cosi-driver package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

SeaweedFS is a distributed storage system. Prior to 4.24, the weed/server/filer_server_handlers.go allowed_prefixes authorization check used strings.HasPrefix on raw path strings, so a filer JWT scoped to /tenant1 also authorized sibling paths such as /tenant1234, /tenant1-old, and /tenant1backup, enabling cross-tenant reads and writes with a valid scoped token. This issue is fixed in version 4.24.
