An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-66785 in the wild and no public exploit code.\n\nAffected product: Red Hat Advanced Cluster Management for Kubernetes 2. 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-2026-66785/ (Markdown: https://insights.sbomify.com/CVE-2026-66785/index.md)","id":"CVE-2026-66785","markdown":"https://insights.sbomify.com/CVE-2026-66785/index.md","name":"CVE-2026-66785","record":{"aliases":["GHSA-37mq-728j-5q43"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes cluster management","requires_auth":"high_privilege","summary":"A malicious cluster can hijack cross-cluster traffic by publishing unvalidated network endpoints, leading to information disclosure or disruption.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption.","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":"Missing authorization in Red Hat Advanced Cluster Management for Kubernetes 2","id":"CVE-2026-66785","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Submariner: submariner: ipsec.conf stanza injection via remote-supplied cablename and subnets","id":"CVE-2026-66786"},"packages":[],"prev":{"headline":"Submariner-operator: release workflow consumes same-org composite action via mutable @devel branch ref","id":"CVE-2026-66783"},"products":["Red Hat Advanced Cluster Management for Kubernetes 2","Red Hat Advanced Cluster Management for Kubernetes 2.16","Red Hat Advanced Cluster Management for Kubernetes 2.17"],"published":"2026-08-20","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":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Red Hat"]},"summary":"A malicious cluster can hijack cross-cluster traffic by publishing unvalidated network endpoints, leading to information disclosure or disruption.","url":"https://insights.sbomify.com/CVE-2026-66785/"}
