Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-75036 in the wild and no public exploit code.\n\nAffected product: SUSE Fleet. 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-2026-75036/ (Markdown: https://insights.sbomify.com/CVE-2026-75036/index.md)","id":"CVE-2026-75036","markdown":"https://insights.sbomify.com/CVE-2026-75036/index.md","name":"CVE-2026-75036","record":{"aliases":["GHSA-x9m6-xcjr-hpjp"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Fleet GitOps controller","requires_auth":"low_privilege","summary":"Attackers can exfiltrate cluster metadata and network information via DNS requests during Helm template preprocessing in Fleet.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[{"product":"rancher_fleet","vendor":"suse"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/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-918","name":"Server-Side Request Forgery"},{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"A security vulnerability was discovered in Fleet's Helm template preprocessing where templates evaluated by the Fleet controller could reach network resources outside the management cluster. A user who can supply bundle content to a repository referenced by a `GitRepo` resource can cause the Fleet controller to:\n- Disclose cluster metadata available to the templating context.\n- Reveal information about hosts reachable from the controller's network position.\nBecause the disclosure channel is name resolution, it may remain effective in environments where outbound traffic is otherwise restricted. The disclosed information is limited to values exposed to the Fleet templating context and to name resolution results. Integrity and availability of managed clusters are not affected.\n\nThis issue affects Fleet:\nfrom 0.12.0 before 0.12.19, \nfrom 0.13.0 before 0.13.15, \nfrom 0.14.0 before 0.14.10, \nfrom 0.15.0 before 0.15.6, and\nfrom 0.16.0 before 0.16.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Fleet: DNS exfiltration via Sprig getHostByName in fleet.yaml Helm template preprocessing","id":"CVE-2026-75036","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Polkit authentication bypass in LACT","id":"CVE-2026-75037"},"packages":[],"prev":{"headline":"Rancher: ext.cattle.io/v1 Token store: cross-user token disclosure via label-selector scoping bypass","id":"CVE-2026-75035"},"products":["Fleet"],"published":"2026-09-03","related":[{"cvss_score":9.9,"headline":"Rancher Fleet vulnerable to cross namespace secret disclosure via unvalidated `valuesFrom` references in Helm Deployer","id":"CVE-2026-44935","kev_date_added":null,"published":"2026-07-02"},{"cvss_score":9.9,"headline":"Helm impersonation bypass of `RESTClientGetter` retains `cluster-admin` during template rendering","id":"CVE-2026-41050","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":8.8,"headline":"Privilege escalation in Rancher","id":"CVE-2026-88808","kev_date_added":null,"published":"2026-09-28"},{"cvss_score":8.8,"headline":"Fleet has PSS Bypass through addLabelsFromOptions in Fleet Agent","id":"CVE-2026-44938","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.3,"headline":"SUSE Rancher Fleet had an Unauthenticated Webhook: Regex Injection via Unsanitized Repository URL Components","id":"CVE-2026-44937","kev_date_added":null,"published":"2026-07-06"},{"cvss_score":7.1,"headline":"Missing authorization in Rancher","id":"CVE-2026-93538","kev_date_added":null,"published":"2026-09-28"},{"cvss_score":6.5,"headline":"Path traversal in Fleet Helm valuesFiles allows disclosure of files outside the bundle directory","id":"CVE-2026-93537","kev_date_added":null,"published":"2026-09-28"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-09-05","vendors":["SUSE"]},"summary":"Attackers can exfiltrate cluster metadata and network information via DNS requests during Helm template preprocessing in Fleet.","url":"https://insights.sbomify.com/CVE-2026-75036/"}
