    Regular Expression Denial of Service (ReDoS)

    tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) due to inefficient cookie parsing that results in quadratic performance. An attacker could cause tornado to consume excessive CPU resources and block the event loop through maliciously crafted cookies.

    How to fix Regular Expression Denial of Service (ReDoS)?

    Upgrade tornado to version 6.4.2 or higher.
