An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-105747 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- docling (PyPI): affected from 2.45.0; fixed in 2.131.0\n- docling (PyPI): affected from 2.45.0; fixed in 2.131.0\n- docling (PyPI): affected from 2.45.0; fixed in 2.131.0\n- docling-slim (PyPI): affected from 2.92.0; fixed in 2.131.0\n- docling-slim (PyPI): affected from 2.92.0; fixed in 2.131.0\n- docling-slim (PyPI): affected from 2.92.0; fixed in 2.131.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-105747/ (Markdown: https://insights.sbomify.com/CVE-2026-105747/index.md)","id":"CVE-2026-105747","markdown":"https://insights.sbomify.com/CVE-2026-105747/index.md","name":"CVE-2026-105747","record":{"aliases":["GHSA-3cr3-8m4c-fpxw","PYSEC-2026-4194","PYSEC-2026-4209"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python document processing library","requires_auth":"none","summary":"Attackers can cause memory exhaustion and denial of service by submitting crafted METS-GBS archives to Docling before member limits are enforced.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"docling","vendor":"docling"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-409","name":"Improper Handling of Highly Compressed Data (Data Amplification)"}],"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.
