Details
It was discovered that Addressable incorrectly handled certain URI
templates, generating regular expressions vulnerable to catastrophic
backtracking. An attacker could use this issue to craft a URI that, when matched
against a vulnerable template, causes excessive resource consumption,
leading to a denial of service.
