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.
In this pull request I've also added some valuable remote flow sources which I thought it is related to my query because mostly it need a file upload from Forms as a User Remote Source.

Are you planning to discuss this vulnerability submission publicly? (Blog Post, social networks, etc).

  • Yes
