Docling Core: Insufficient validation of image reference URIs
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | docling-core | >= 2.5.0, < 2.74.1 | 2.74.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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:` and `data:` image references from untrusted input
- allow only approved local or remote image sources
- apply input size and memory limits to processing workers
