Description

An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

1.11 ≤ v < 1.11.111.8 ≤ v < 1.8.192.0 ≤ v < 2.0.3
Affected range stops below 1.11.11, so it looks safe — our inference, not a vendor statement
Affected range stops below 1.8.19, so it looks safe — our inference, not a vendor statement
Affected range stops below 2.0.3, so it looks safe — our inference, not a vendor statement
