Overview
Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the chars() and words() methods in the django.utils.text.Truncator function. An attacker can cause a denial of service by exploiting the inefficient regular expression complexity, which exhibits linear backtracking complexity and can be slow, given certain long and potentially malformed HTML inputs.
