Lifecycle Timeline
5DescriptionCVE.org
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.
AnalysisAI
Uncontrolled resource consumption in wger before 2.5 allows any authenticated user to exhaust server worker threads and deny service to all legitimate users. By creating a routine with an arbitrarily long date range (e.g., 100 years spanning 2000-2099) and then triggering the unbounded date_sequence while-loop via any of five routine detail REST endpoints, a single HTTP request forces 36,525 per-day iterations - each performing O(slots × entries × configs) computation - consuming multiple seconds of CPU. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must hold a valid authenticated account on the target wger instance (CVSS PR:L); in deployments with open self-registration this requires only completing account creation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 (AV:N/AC:L/AT:N/PR:L/UI:N/VA:H) accurately reflects the threat model. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | A fix commit (5f07a4473e2c32d298c8cdd31d78e5107840039c) exists in the wger GitHub repository and adds maximum-duration validation to the Routine model and serializer. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Implement rate limiting on the five affected routine detail REST endpoints-restrict each authenticated user to 1-2 requests per minute per endpoint and add 30-second request timeouts to prevent worker thread exhaustion. …
