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-2026-20195 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-2026-20195/ (Markdown: https://insights.sbomify.com/CVE-2026-20195/index.md)","id":"CVE-2026-20195","markdown":"https://insights.sbomify.com/CVE-2026-20195/index.md","name":"CVE-2026-20195","record":{"aliases":["GHSA-63pc-j336-8qq4"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Identity Services Engine","requires_auth":"none","summary":"Unauthenticated attackers can enumerate valid user accounts by analyzing error messages from the identity management API endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"identity_services_engine","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-204","name":"Observable Response Discrepancy"}],"description":"A vulnerability in an identity management API endpoint of Cisco ISE could allow an unauthenticated, remote attacker to enumerate valid user accounts on an affected device.\r\n\r\nThis vulnerability exists because error messages are observed when the affected API endpoint is called.
