path-to-regexp outputs backtracking regular expressions

Impact A bad regular expression is generated any time you have two parameters within a single segment, separated by something that is not a period .. For example, /:a-:b. Patches For users of 0.1, upgrade to 0.1.10. All other users should upgrade to 8.0.0. These versions add backtrack protection...

The vulnerability of the Django web application framework, related to the inefficient complexity of regular expressions, allows attackers to trigger a service failure.

The vulnerability of the Django web application framework relates to regular expressions for text trimming, which have linear complexity in their reverse path computation, potentially leading to slow performance. Exploiting this vulnerability could allow a remote attacker to cause service...
