{"cve":"CVE-2026-75036","nvd":{"published":"2026-09-03T16:18:22.607","modified":"2026-10-07T15:08:40.547","status":"Analyzed","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.","cvss_v4":{"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","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-918","CWE-1336"],"references":["https://github.com/rancher/fleet/security/advisories/GHSA-x9m6-xcjr-hpjp"],"products":["suse:rancher_fleet"],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-75036","score":0.00162,"percentile":0.05302,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
