PYSEC-2026-2456
No affected components available
Impact
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.
Patches
Patched in docling-core 2.74.1.
The fix blocks local file URIs by default and adds a size limit for decoded inline image data.
Users should upgrade to:
docling-core>= 2.74.1
Workarounds
If upgrading is not immediately possible:
- reject
file:anddata:image references from untrusted input - allow only approved local or remote image sources
- apply input size and memory limits to processing workers

v2.74.1
