Real-World Exposure

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

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

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for docling-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update docling-core to 2.74.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j5xp-7m2f-49jv is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Frequently Asked Questions

### 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.
