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-2026-20320 in the wild and no public exploit code.\n\nAffected product: Cisco BroadWorks. 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-2026-20320/ (Markdown: https://insights.sbomify.com/CVE-2026-20320/index.md)","id":"CVE-2026-20320","markdown":"https://insights.sbomify.com/CVE-2026-20320/index.md","name":"CVE-2026-20320","record":{"aliases":["GHSA-9w8j-fg77-whw7"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco BroadWorks","requires_auth":"none","summary":"Unauthenticated remote attackers can read sensitive configuration files via XML external entity injection in the OCI-P service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","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-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A vulnerability in the Open Client Interface (OCI) XML Parser of Cisco BroadWorks could allow an unauthenticated, remote attacker to read sensitive configuration information on an affected system.\r\n\r This vulnerability exists because XML entries are improperly parsed due to external entity resolution being allowed by default.
