CWE-820Missing Synchronization
The product utilizes a shared resource in a concurrent manner but does not attempt to synchronize access to the resource.
If access to a shared resource is not synchronized, then the resource may not be in a state that is expected by the product. This might lead to unexpected or insecure behaviors, especially if an attacker can influence the shared resource.
