Overview
Affected versions of this package are vulnerable to Missing Authorization in the configMapSyncProvider process. An attacker can create, read, update, or delete Kubernetes ConfigMaps containing synchronization limits by sending crafted requests with any Bearer token, including fake tokens, to the Sync Service endpoints. This can result in denial of service by setting restrictive sync limits, disruption of workflow execution, disclosure of sensitive configuration data, or arbitrary manipulation of ConfigMaps.
