## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-3cr3-8m4c-fpxw. This link is maintained to preserve external references.

## Original Description
Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.45.0 until 2.131.0, METS-GBS format detection in docling/datamodel/document.py and the backend in docling/backend/mets_gbs_backend.py call tarfile.TarFile.getmembers() before enforcing the max_member_count limit, causing the full archive member list to be allocated before the limit can stop processing. A small gzip-compressed tar archive with a very large number of empty members can therefore consume memory proportional to the declared member count, including during format detection before the allowed_formats restriction is applied. This issue is a residual weakness in the member-count protection added for CVE-2026-44018. This issue is fixed in 2.131.0.

## Affected packages

- `docling >= 2.45.0, < 2.131.0`

## Remediation

Upgrade to a patched release:

- `docling 2.131.0`
