CVE-2026-86255 PUBLISHED

wger before 2.5 Uncontrolled Resource Consumption via date_sequence

Assigner: VulnCheck
Reserved: 06.09.2026 Published: 06.09.2026 Updated: 06.09.2026

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.
