CVE-2026-44019: Docling Core: Insufficient validation of image reference URIs

In versions >= 2.5.0, < 2.74.1, docling-core could allow local file:// image references and accepted inline data: content without a decoded-size limit.

In applications that accept untrusted image references, this may allow access to local files readable by the process or excessive memory use from large inline payloads.
