NVD Description

Note: Versions mentioned in the description apply only to the upstream tough-cookie.src package and not the tough-cookie.src package as distributed by RHEL.

Versions of the package tough-cookie before 4.1.3 are vulnerable to Prototype Pollution due to improper handling of Cookies when using CookieJar in rejectPublicSuffixes=false mode. This issue arises from the manner in which the objects are initialized.
