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-2026-72895 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC IPC BX-21A. 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-2026-72895/ (Markdown: https://insights.sbomify.com/CVE-2026-72895/index.md)","id":"CVE-2026-72895","markdown":"https://insights.sbomify.com/CVE-2026-72895/index.md","name":"CVE-2026-72895","record":{"aliases":["GHSA-f9v9-v28p-r5mp"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["security_bypass","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens SIMATIC IPC","requires_auth":"none","summary":"A BIOS vendor test key in UEFI Secure Boot allows local attackers to bypass security protections and boot unauthorized operating systems or applications.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1394","name":"Use of Default Cryptographic Key"}],"description":"A vulnerability has been identified in SIMATIC IPC BX-21A (All versions \u003c V31.01.13), SIMATIC IPC RW-543A (All versions \u003c V1.1.4), SIMATIC IPC227G / IPC277G / IPC277G PRO / IPC327G / IPC377G (All versions \u003c V28.01.15).
