Overview
Affected versions of this package are vulnerable to Improper Authorization via the canonicalization process for namespace paths. An attacker can gain unauthorized management access to the containing namespace by supplying the special path segment "root" in requests to endpoints under /sys/namespaces/*, allowing them to perform operations such as lookup, deletion, locking, or patching custom metadata on the namespace. This is only exploitable if the user has been granted management capabilities on /sys/namespaces/root within a non-root namespace.
