Summary

wger before 2.5 Uncontrolled Resource Consumption via date_sequence

Details

wger before 2.5 fails to validate the maximum duration of routine date ranges, allowing authenticated users to create routines spanning arbitrarily long periods. Attackers can trigger the date_sequence computation via routine detail endpoints, forcing the server to iterate thousands of times per request and exhaust worker threads, denying service to legitimate users.
