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-2026-23811 in the wild and no public exploit code.\n\nAffected product: Arubanetworks Arubaos. 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-2026-23811/ (Markdown: https://insights.sbomify.com/CVE-2026-23811/index.md)","id":"CVE-2026-23811","markdown":"https://insights.sbomify.com/CVE-2026-23811/index.md","name":"CVE-2026-23811","record":{"aliases":["GHSA-99rv-pxvm-xph4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HPE Aruba Wireless OS","requires_auth":"none","summary":"Attackers can bypass client isolation and redirect traffic to perform Machine-in-the-Middle attacks on HPE Aruba wireless networks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hpe","cpe":[{"product":"arubaos","vendor":"arubanetworks"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-300","name":"Channel Accessible by Non-Endpoint"}],"description":"A vulnerability in the client isolation mechanism may allow an attacker to bypass Layer 2 (L2) communication restrictions between clients and redirect traffic at Layer 3 (L3).
