Overview
Affected versions of this package are vulnerable to Incorrect Authorization through the replicationTaskExecutor process. An attacker can alter the state, description, owner, retention, archival settings, and cluster list of local namespaces by sending crafted inbound namespace replication tasks from a connected peer cluster. This can result in unauthorized changes such as marking namespaces as deprecated, changing the active cluster, or shortening retention, potentially causing workflow failures. This is only exploitable if a remote cluster is registered with connection enabled and is controlled or compromised by an attacker.
