The issue is related to a Missing Authorization vulnerability in the Download All Files module for the Drupal CMS, which allows for Forceful Browsing. This vulnerability can be exploited by a remote attacker to bypass security restrictions and perform a forceful browsing attack.

The issue is related to improper header parsing in the guzzlehttp/psr7 library. An attacker could sneak in a new line character and pass untrusted values in both the header names and values. This could potentially allow a remote attacker to impact the integrity of protected information.
