It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-5444 in the wild and no public exploit code.\n\nAffected product: Orthanc DICOM Server. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-5444/ (Markdown: https://insights.sbomify.com/CVE-2026-5444/index.md)","id":"CVE-2026-5444","markdown":"https://insights.sbomify.com/CVE-2026-5444/index.md","name":"CVE-2026-5444","record":{"aliases":["DEBIAN-CVE-2026-5444","GHSA-fpm7-vpjm-5gg2","UBUNTU-CVE-2026-5444"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DICOM Server","requires_auth":"none","summary":"An attacker can trigger a heap buffer overflow in Orthanc by sending a crafted DICOM file, potentially leading to code execution or service disruption.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"orthanc","vendor":"orthanc-server"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A heap buffer overflow vulnerability exists in the PAM image parsing logic.
