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-2026-28199 in the wild and no public exploit code.\n\nAffected product: Cohesity NetBackup Flex OS. 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-2026-28199/ (Markdown: https://insights.sbomify.com/CVE-2026-28199/index.md)","id":"CVE-2026-28199","markdown":"https://insights.sbomify.com/CVE-2026-28199/index.md","name":"CVE-2026-28199","record":{"aliases":["GHSA-chmq-8gh3-838c"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NetBackup Flex OS","requires_auth":"low_privilege","summary":"Authenticated users can read arbitrary files via path traversal in the management shell, exposing sensitive system data.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ENISA","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"An authenticated user with access to the NetBackup Flex OS management \nshell could read arbitrary files from the underlying operating system by\n supplying a specially crafted path argument to a diagnostic command. \nSuccessful exploitation could expose sensitive system configuration and \ncredential material stored on the appliance.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Sensitive File Disclosure via Relative Path Traversal in NetBackup Flex OS Shell","id":"CVE-2026-28199","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"SurrealDB Injection on Open Notebook","id":"CVE-2026-28201"},"packages":[],"prev":{"headline":"Privilege Escalation via Cryptographic Signature Verification Bypass in NetBackup Flex OS Shell","id":"CVE-2026-28198"},"products":["NetBackup Flex OS"],"published":"2026-09-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["Cohesity"]},"summary":"Authenticated users can read arbitrary files via path traversal in the management shell, exposing sensitive system data.","url":"https://insights.sbomify.com/CVE-2026-28199/"}
