Description
Treeio through 2.0 contains an insecure deserialization vulnerability in UpdateRecord.get_format_strings and ModuleSetting.loads that allows staff users to execute code via unverified pickle data. Attackers can store a crafted base64 pickle payload in an UpdateRecord format_strings field through the Django admin, executing Python code as the web server user when news feeds render.
