{"id":"CVE-2026-65835","summary":"Capsule: Incomplete fix of CVE-2026-22872: TenantResource RawItems and Generators still allow cluster-scoped resource creation (cross-tenant privilege escalation)","details":"Capsule is a multi-tenancy and policy-based framework for Kubernetes. From 0.13.0 until 0.13.8, after the incomplete CVE-2026-22872 fix, TenantResource RawItems and Generators in internal/controllers/resources/collect.go, including handleRawItem and handleGeneratorItem, did not apply the ResourceReference.LoadResources and IsNamespacedGVK cluster-scoped resource rejection guard used by NamespacedItems, allowing a Tenant Owner to create cluster-scoped resources such as ClusterRole or ValidatingWebhookConfiguration through the cluster-admin controller client. This issue is fixed in version 0.13.8.","aliases":["GHSA-jr6p-8pjj-mfx6","GO-2026-6157"],"modified":"2026-09-09T18:26:47.592897807Z","published":"2026-07-30T19:53:52.769Z","related":["openSUSE-SU-2026:21761-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65835.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/projectcapsule/capsule/releases/tag/v0.13.8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65835.json"},{"type":"ADVISORY","url":"https://github.com/projectcapsule/capsule/security/advisories/GHSA-jr6p-8pjj-mfx6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65835"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/projectcapsule/capsule","events":[{"introduced":"c6e109ca46ed7de3a0f371df75e8abc993413a64"},{"fixed":"4b07463705d6eebcaabffcabd77d401ef7a809f3"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0.13.0"},{"fixed":"0.13.8"}]}}],"versions":["v0.13.7","v0.13.6","v0.13.5","v0.13.4","v0.13.3","v0.13.2","v0.13.1","v0.13.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-65835.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L"}]}
