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-2026-20188 in the wild and no public exploit code.\n\nAffected product: Cisco Crosswork Network Change Automation. 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-2026-20188/ (Markdown: https://insights.sbomify.com/CVE-2026-20188/index.md)","id":"CVE-2026-20188","markdown":"https://insights.sbomify.com/CVE-2026-20188/index.md","name":"CVE-2026-20188","record":{"aliases":["GHSA-m776-2hwc-9x9m"],"analysis":{"component_type":"network_device","fix_type":"configuration_change","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco Network Controller","requires_auth":"none","summary":"Cisco reclassified a DoS issue in Crosswork Network Controller and NSO as a customer-configurable resource management problem, not a security vulnerability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":0,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Following the initial publication of the Security Advisory about a denial of service (DoS) condition in Cisco Crosswork Network Controller and Cisco Network Services Orchestrator (NSO), additional information has been made available to the Cisco Product Security Incident Response Team (PSIRT).\r\n\r\nUpon further analysis, the Cisco PSIRT has reclassified this issue as a customer-configurable, resource management issue rather than a security vulnerability.","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":"Cisco Crosswork Network Controller and Cisco Network Services Orchestrator Advisory","id":"CVE-2026-20188","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Prime Infrastructure Information Disclosure Vulnerability","id":"CVE-2026-20189"},"packages":[],"prev":{"headline":"Cisco RoomOS Security Hardening Release - Exceptional Conditions Handling Vulnerabilities","id":"CVE-2026-20187"},"products":["Cisco Crosswork Network Change Automation"],"published":"2026-05-06","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-14","vendors":["Cisco"]},"summary":"Cisco reclassified a DoS issue in Crosswork Network Controller and NSO as a customer-configurable resource management problem, not a security vulnerability.","url":"https://insights.sbomify.com/CVE-2026-20188/"}
