SCA: security update for wagtail (GHSA-wq5h-f9p5-q7fx)

high Tenable Cloud Security Plugin ID 420061

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Wagtail is a Django content management system. In affected versions of Wagtail, when saving the contents
of a rich text field in the admin interface, Wagtail does not apply server-side checks to ensure that link
URLs use a valid protocol. A malicious user with access to the admin interface could thus craft a POST
request to publish content with `javascript:` URLs containing arbitrary code. The vulnerability is not
exploitable by an ordinary site visitor without access to the Wagtail admin. See referenced GitHub
advisory for additional details, including a workaround. Patched versions have been released as Wagtail
2.11.7 (for the LTS 2.11 branch) and Wagtail 2.12.4 (for the current 2.12 branch). (CVE-2021-29434)
