Description

Server-side request forgery in the METS and IIIF import URI handling in Scripta eScriptorium through 26.04.1 allows a remote authenticated user to make the server issue arbitrary HTTP requests to internal hosts, including the cloud instance metadata service, via the mets_uri or iiif_uri parameter of POST /api/documents/{pk}/imports/, because the IMPORT_ALLOWED_DOMAINS setting defaults to '*' and no address filtering, redirect cap or timeout is applied
