wagtail is vulnerable to Denial of Service (DoS)

Medium Risk
This Affects:
wagtailTL;DR
The image preview endpoint accepts arbitrary filter specs without restricting the allowed operations. An authenticated Wagtail admin user can request purposefully crafted filter specs that trigger expensive rendition processing. This can lead to service degradation through uncontrolled resource consumption. The fix limits the preview endpoint to a small set of allowed filter operations.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and grant users access to the Wagtail admin.
