Report

Extracting Compressed files with any compression algorithm like gzip can cause to denial of service attacks. Attackers can compress a huge file which created by repeated similar byte and convert it to a small compressed file.
Added modeling for multiple CLI third parties.
I've added FileAndFormRemoteFlowSource module which is related to all queries that need a file as their user provided remote flow sources. in this module I added support of file and form of FastAPI framework.
I tried my best to add as much sanitizers as possible. if you have another idea about sanitizers I can write more sanitizers too.
