It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18849 in the wild and no public exploit code.\n\nAffected product: IBM OPENBMC. 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-2026-18849/ (Markdown: https://insights.sbomify.com/CVE-2026-18849/index.md)","id":"CVE-2026-18849","markdown":"https://insights.sbomify.com/CVE-2026-18849/index.md","name":"CVE-2026-18849","record":{"aliases":["GHSA-5j8f-fc55-9mwx"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM OpenBMC firmware","requires_auth":"high_privilege","summary":"Authenticated administrators can execute arbitrary code via path traversal in the BMC firmware update process, compromising system integrity.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"openbmc","vendor":"ibm"},{"product":"power_system_e1050_\\(9043-mrx\\)_firmware","vendor":"ibm"},{"product":"power_system_l1022_\\(9786-22h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1024_\\(9786-42h\\)_firmware","vendor":"ibm"},{"product":"power_system_s1012_\\(9028-21b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1014_\\(9105-41b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1022_\\(9105-22a\\)_firmware","vendor":"ibm"},{"product":"power_system_s1022s_\\(9105-22b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1024_\\(9105-42a\\)_firmware","vendor":"ibm"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"IBM OpenBMC FW1060.00 through FW1060.80 is affected by a vulnerability in the BMC firmware update process.
