CVE-2026-18359
HighCVSS 8.5Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
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
Risk Assessment
The risk includes the possibility of accessing internal network resources, which could lead to data leakage or privilege escalation. The attack requires authentication, but can be carried out by any logged-in user.
Recommendation
It is recommended to configure the IMPORT_ALLOWED_DOMAINS setting to a list of trusted domains and implement IP address filtering and timeouts. Also, update the software to a version that contains the fix.
Other vulnerabilities in Scripta eScriptorium
See all- CVE-2026-18277High
Missing authorization in the OcrModelRight create and delete views in Scripta eScriptorium through 26.04.1 allows a remote authenticated user to grant themselves access to another user's private OCR model and to revoke any user's OCR model access via a POST request, because the ownership check is placed in get_context_data() and therefore runs only on the GET rendering path
- CVE-2026-18258High
Authorization bypass in the Line, LineTranscription, VirtualCollection, tag and process API endpoints in Scripta/eScriptorium through 26.04.1 allows a remote authenticated user to read, modify and delete other users' transcription content via primary keys supplied in the request body, which are queried against the global model manager instead of the request-scoped queryset
