Docling Core: Unsafe remote filename resolution

  • Disclosed: 03.06.2026
  • Updated: 11.10.2026 14:18

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.
