@ziadhany thanks! Can you do a quick check to see if two advisories does not share same AVID ? Please run the query and share the results. Also do it for the next set of importers that you are gonna do as well. Thanks!

I ran the epss twice and this is the result in my local database:

>>  from vulnerabilities.models import AdvisoryV2
>>  from django.db.models import Count
>> duplicates = (
    AdvisoryV2.objects
    .values('avid')
    .annotate(count=Count('id'))
    .filter(count__gt=1)
)
>> print(len(duplicates))
332422

Clear the DB, run it once. And then let me know. Does it have any dupe AVIDs. Thanks!

There is no duplication in EPSS Importer v2 when the importer is run once.

>> from vulnerabilities.models import AdvisoryV2
>> from django.db.models import Count
>> duplicates = (
    AdvisoryV2.objects
    .values('avid')
    .annotate(count=Count('id'))
    .filter(count__gt=1)
)
>> duplicates
Out[10]: <AdvisoryQuerySet []>
>> len(duplicates)
Out[11]: 0

>> AdvisoryV2.objects.count()
Out[21]: 307387
