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-2026-81581 and fix it if it is affected.\n\nWhat it is: CVE-2026-81581 is a high-severity memory corruption vulnerability in wibu-systems-ag wibukey, published on 27 Aug 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-2026-81581 in the wild and no public exploit code.\n\nAffected product: wibu-systems-ag wibukey. 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-2026-81581/ (Markdown: https://insights.sbomify.com/CVE-2026-81581/index.md)","id":"CVE-2026-81581","markdown":"https://insights.sbomify.com/CVE-2026-81581/index.md","name":"CVE-2026-81581","record":{"aliases":["GHSA-m4jv-48jv-489g"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows driver","requires_auth":"low_privilege","summary":"Attackers can trigger a denial of service or potentially escalate privileges via improper memory boundary validation in the WibuKey Windows driver.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wibu","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Improper validation of memory boundaries in WibuKey64.sys of WibuKey up to 6.70 for Windows can be exploited by an attacker by setting the pointers outside the scope of the program.
