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-2026-6794 in the wild and no public exploit code.\n\nAffected product: Ibm Concert. 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-2026-6794/ (Markdown: https://insights.sbomify.com/CVE-2026-6794/index.md)","id":"CVE-2026-6794","markdown":"https://insights.sbomify.com/CVE-2026-6794/index.md","name":"CVE-2026-6794","record":{"aliases":["GHSA-2vvc-x872-gvjq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Concert software","requires_auth":"low_privilege","summary":"A local attacker can exploit a double free vulnerability in IBM Concert to corrupt heap memory and execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"concert","vendor":"ibm"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"IBM Concert 1.0.0 through 3.0.0 has a double free vulnerability that exists due to incorrect memory management.
