It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-18857 and fix it if it is affected.\n\nWhat it is: CVE-2026-18857 is a low-severity vulnerability in IBM OPENBMC, published on 24 Sep 2026. 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-2026-18857 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-2026-18857/ (Markdown: https://insights.sbomify.com/CVE-2026-18857/index.md)","id":"CVE-2026-18857","markdown":"https://insights.sbomify.com/CVE-2026-18857/index.md","name":"CVE-2026-18857","record":{"aliases":["GHSA-34jw-2gcw-f6v2"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM OpenBMC firmware","requires_auth":"high_privilege","summary":"A vulnerability in IBM OpenBMC firmware allows the host system to crash the BMC service or read internal memory, impacting confidentiality and availability.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"power_system_e1050_\\(9043-mrx\\)_firmware","vendor":"ibm"},{"product":"power_system_e1150_\\(9043-mru\\)_firmware","vendor":"ibm"},{"product":"power_system_l1022_\\(9786-22h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1024_\\(9786-42h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1122_\\(9856-22h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1124_\\(9856-42h\\)_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"},{"product":"power_system_s1112_\\(9242-21b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1112_\\(9242-21t\\)_firmware","vendor":"ibm"},{"product":"power_system_s1114_\\(9824-41b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1122_\\(9824-22a\\)_firmware","vendor":"ibm"},{"product":"power_system_s1122s_\\(9824-22b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1124_\\(9824-42a\\)_firmware","vendor":"ibm"}],"cvss":{"score":3.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"IBM OPENBMC FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, and FW1060.00 through FW1060.81 is affected by a vulnerability in the BMC firmware management interface.
