# Wagtail 2.7.3 release notes

*May 4, 2020*

## CVE-2020-11037: Potential timing attack on password-protected private pages

This release addresses a potential timing attack on pages or documents that have been protected with a shared password through Wagtail’s “Privacy” controls. This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. (This is [understood to be feasible on a local network, but not on the public internet](https://groups.google.com/d/msg/django-developers/iAaq0pvHXuA/fpUuwjK3i2wJ).)

Many thanks to Thibaud Colas for reporting this issue.
