Wagtail: Denial of service via unbounded filter specs in the image preview

Title source: cna
STIX 2.1

Description

Wagtail is an open source content management system built on Django. In versions prior to 7.0.8, 7.3.3 and 7.4.2, an authenticated admin user can trigger expensive rendition processing with purposefully crafted filter specs resulting in potentially service degradation. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. This issue has been fixed in versions 7.0.8, 7.3.3, and 7.4.2.
