Who should care

Administrators and users of Scripta eScriptorium instances, especially those with multi-user environments, should be aware of this vulnerability and take necessary precautions to prevent exploitation. This includes reviewing and restricting access to sensitive document parts, monitoring for suspicious activities, and implementing compensating controls.

Technical summary

The process and annotation taxonomy serializers in Scripta eScriptorium through 26.04.1 have an authorization bypass vulnerability allowing remote authenticated users to run segmentation and transcription against other users' document parts, potentially overwriting their content. This vulnerability can be exploited by remote authenticated users with limited privileges, potentially leading to unauthorized content modifications.
