Threats affecting pkg:github/scripta/escriptorium

CVE-2026-18277 is a missing authorization vulnerability in Scripta eScriptorium versions prior to 26.04.2. It allows a remote authenticated user to grant themselves access to another user's private OCR model and revoke access for any user via POST requests. The flaw exists because the ownership check is only performed during GET requests, not during POST operations that modify access.

CVE-2026-18359 is a server-side request forgery (SSRF) vulnerability in Scripta eScriptorium versions prior to 26.04.2. It arises from the METS and IIIF import URI handling, where an authenticated remote user can cause the server to make arbitrary HTTP requests to internal hosts. This is due to the default setting of IMPORT_ALLOWED_DOMAINS to '*' and the lack of address filtering, redirect caps, or timeouts on the mets_uri or iiif_uri parameters in the import API endpoint.
