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-2026-20136 in the wild and no public exploit code.\n\nAffected product: Cisco Identity Services Engine. 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-2026-20136/ (Markdown: https://insights.sbomify.com/CVE-2026-20136/index.md)","id":"CVE-2026-20136","markdown":"https://insights.sbomify.com/CVE-2026-20136/index.md","name":"CVE-2026-20136","record":{"aliases":["GHSA-hj84-36vf-hc6f"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco ISE","requires_auth":"high_privilege","summary":"An authenticated local attacker with admin privileges can inject commands into the CLI to escalate privileges to root on Cisco ISE.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"identity_services_engine","vendor":"cisco"},{"product":"identity_services_engine_passive_identity_connector","vendor":"cisco"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"A vulnerability in the\u0026nbsp;CLI of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, local attacker with administrative privileges to perform a command injection attack on the underlying operating system and elevate privileges to root.\r\n\r\nThis vulnerability is due to insufficient validation of user supplied input.
