Django is vulnerable to Regular Expression Denial Of Service. The vulnerability is due to the chars and words functions in text.py as there is no proper limiting or optimization while using regular expressions to parse and truncate input text. This allows an attacker to craft very long or potentially malformed HTML input, that makes the evaluation excessively slow and potentially leads to a DOS.
