It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-20128 in the wild since at least 20 Apr 2026.\n\nAffected product: Cisco Catalyst Sd-Wan Manager. 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-2026-20128/ (Markdown: https://insights.sbomify.com/CVE-2026-20128/index.md)","id":"CVE-2026-20128","markdown":"https://insights.sbomify.com/CVE-2026-20128/index.md","name":"CVE-2026-20128","record":{"aliases":["GHSA-mp6j-7g85-8pg2"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco SD-WAN Manager","requires_auth":"high_privilege","summary":"An unauthenticated remote attacker can read a credential file to gain DCA user privileges on Cisco Catalyst SD-WAN Manager systems.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"catalyst_sd-wan_manager","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-257","name":"Storing Passwords in a Recoverable Format"}],"description":"A vulnerability in the Data Collection Agent (DCA) feature of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to gain DCA user privileges on an affected system.\r\n\r\nThis vulnerability is due to the presence of a credential file for the DCA user on an affected system.
