Improper Control of Interaction Frequency Affecting django-smart-ratelimit package, versions [,0.3.2)

django-smart-ratelimit is an A flexible and efficient rate limiting library for Django applications

Affected versions of this package are vulnerable to Improper Control of Interaction Frequency via counter.save() function that does not implement atomic increments. In the fixed-window backend concurrent requests can overwrite each other’s increments and lead to rate limit bypass. In the sliding-window backend, the delete/create steps are not wrapped in a transaction.atomic(), allowing inconsistent state under load.
