An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76721 in the wild and no public exploit code.\n\nAffected product: Hewlett Packard Enterprise (HPE) Instant ON. 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-2026-76721/ (Markdown: https://insights.sbomify.com/CVE-2026-76721/index.md)","id":"CVE-2026-76721","markdown":"https://insights.sbomify.com/CVE-2026-76721/index.md","name":"CVE-2026-76721","record":{"aliases":["GHSA-pw85-jqmm-v352"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"HPE Instant ON AP","requires_auth":"none","summary":"Unauthenticated remote attackers can exploit a buffer overflow in HPE Instant ON APs to execute arbitrary code with privileged access.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hpe","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/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":"Buffer overflow vulnerability exists in the affected interface of HPE Networking Instant ON that could allow an unauthenticated remote attacker to run arbitrary code on the underlying host.
