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-2026-5267 in the wild and no public exploit code.\n\nAffected product: Ciena Navigator NCS. 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-2026-5267/ (Markdown: https://insights.sbomify.com/CVE-2026-5267/index.md)","id":"CVE-2026-5267","markdown":"https://insights.sbomify.com/CVE-2026-5267/index.md","name":"CVE-2026-5267","record":{"aliases":["GHSA-6mqq-ppj3-rm94"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Network Control Suite","requires_auth":"none","summary":"Unauthenticated attackers can access event streams to obtain sensitive session tokens in Ciena Navigator NCS.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Ciena","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Ciena Navigator Network\nControl Suite (NCS) contains an information exposure vulnerability in an\nevent-streaming API that does not properly enforce authentication.
