An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-72712 exists.\n\nAffected product: Nmap. 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-2026-72712/ (Markdown: https://insights.sbomify.com/CVE-2026-72712/index.md)","id":"CVE-2026-72712","markdown":"https://insights.sbomify.com/CVE-2026-72712/index.md","name":"CVE-2026-72712","record":{"aliases":["AZL-95529","CLSA-2026-1789630245","CLSA-2026-1790157825","DEBIAN-CVE-2026-72712","ECHO-6a0e-ede1-c771","GHSA-7j7x-fg87-hwwg","MGASA-2026-0433","OESA-2026-3679","OESA-2026-3680","OESA-2026-3681","OESA-2026-3682","OESA-2026-3745","UBUNTU-CVE-2026-72712"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Network scanning tool","requires_auth":"none","summary":"Remote attackers can crash Nmap by sending crafted packets with zero-length TCP options, causing an infinite loop and out-of-memory condition.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"Nmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option.
