QID 983128: Python (pip) Security Update for wagtail (GHSA-jjjr-3jcw-f8v6)

Security update has been released for wagtail to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

A potential timing attack exists 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).)

Privacy settings that restrict access to pages / documents on a per-user or per-group basis (as opposed to a shared password) are unaffected by this vulnerability.

  • CVSS V3 rated as Medium - 4.7 severity.
  • CVSS V2 rated as Low - 1.9 severity.
    • Solution
    Patched versions have been released as Wagtail 2.7.3 (for the LTS 2.7 branch), Wagtail 2.8.2 and Wagtail 2.9.Workaround:
    Site owners who are unable to upgrade to the new versions can use [user- or group-based privacy restrictions](https://docs.wagtail.io/en/stable/advanced_topics/privacy.html) to restrict access to sensitive information; these are unaffected by this vulnerability.
