Authorization bypass in the process and annotation taxonomy serializers in Scripta eScriptorium through 26.04.1 allows a remote authenticated user to run segmentation and transcription against other users' document parts, overwriting their content, via part primary keys supplied to a many=True related field whose queryset restriction was applied to the ManyRelatedField instead of its child_relation and therefore had no effect
Upgrade to fixed version: 26.04.2, 1.0.1 or 0.13.9.
