How to Fix CVE-2026-44023

To remediate this vulnerability, upgrade all affected Docling Core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

docling-core fixed: 2.74.1
pip install docling-core>=2.74.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

pip show docling-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-44023, inspect your installed packages using pip:

pip show docling-core

Analyze the terminal output to locate any version of Docling Core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.74.1), your application is affected.

Note: The pip show docling-core command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Docling Core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In versions `>= 1.5.0, < 2.74.1`, `docling-core` did not sufficiently restrict remote request destinations and could resolve a server-provided `Content-Disposition` to a local path in an unsafe manner. In applications that accept untrusted URLs, this could allow SSRF attacks targeting local files outside the user-defined cache directory. ### Patches Patched in `docling-core` `2.74.1`. The fix adds stricter validation for remote destinations and normalizes server-provided filenames before use. Users should upgrade to: - `docling-core` `>= 2.74.1` ### Workarounds If upgrading is not immediately possible, avoid passing untrusted URLs into remote fetch functionality. ### References - Fix release: [`v2.74.1`](https://github.com/docling-project/docling-core/releases/tag/v2.74.1)
