{"id":"CVE-2026-65834","summary":"Capsule: CapsuleConfiguration NodeMetadata regex fields lack webhook validation, allowing MustCompile panic on all Node admission requests","details":"Capsule is a multi-tenancy and policy-based framework for Kubernetes. Prior to 0.13.8, CapsuleConfiguration.Spec.NodeMetadata.ForbiddenLabels.Regex and CapsuleConfiguration.Spec.NodeMetadata.ForbiddenAnnotations.Regex were not validated by the configuration admission webhook, allowing a Cluster Admin to store a malformed regex that later reached regexp.MustCompile in pkg/api/forbidden_list.go through internal/webhook/node/user_metadata.go and crashed the node admission webhook on Node create, update, or patch requests. This issue is fixed in version 0.13.8.","aliases":["GHSA-68cj-mvg9-rgm2","GO-2026-6155"],"modified":"2026-09-09T18:26:42.088296630Z","published":"2026-07-30T19:48:55.027Z","related":["openSUSE-SU-2026:21761-1"],"database_specific":{"cwe_ids":["CWE-20","CWE-248"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65834.json","cna_assigner":"GitHub_M"},"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-2026-65834.json"},{"type":"ADVISORY","url":"https://github.com/projectcapsule/capsule/security/advisories/GHSA-68cj-mvg9-rgm2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65834"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/projectcapsule/capsule","events":[{"introduced":"0"},{"fixed":"4b07463705d6eebcaabffcabd77d401ef7a809f3"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"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","v0.11.2","v0.12.4","v0.12.3","v0.12.2","v0.12.1","v0.12.0","v0.11.1","v0.11.0","v0.10.9","v0.10.8","v0.10.7","v0.10.6","v0.10.5","v0.10.4","v0.10.3","v0.10.2","v0.10.1","v0.10.0","v0.9.0","v0.8.1","v0.8.0","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.7.0-rc.1","v0.6.2","v0.6.1","v0.6.0","v0.6.0-rc0","helm-v0.6.0","v0.5.0","v0.4.2","helm-v0.5.3","v0.4.1","helm-v0.5.2","helm-v0.5.1","helm-v0.4.7","v0.4.0","v0.4.0-rc.3","helm-v0.5.0","v0.4.0-rc.2","v0.4.0-rc.1","helm-v0.4.8","helm-v0.4.6","v0.3.3","helm-v0.4.4","v0.3.2","helm-v0.4.3","helm-v0.4.2","v0.3.1","helm-v0.4.1","v0.3.0","helm-v0.4.0","helm-v0.3.6","helm-v0.3.5","v0.2.1","helm-v0.3.1","helm-v0.3.4","helm-v0.3.3","helm-v0.3.2","v0.2.0","helm-v0.3.0","helm-v0.2.0","v0.1.3","helm-v0.1.12","v0.1.2","helm-v0.1.11","helm-v0.1.10","v0.1.2-rc1","v0.1.2-rc0","helm-v0.1.8","helm-v0.1.7","helm-v0.1.6","v0.1.1","helm-v0.1.4","v0.1.1-rc1","helm-v0.1.3","helm-v0.1.2","helm-v0.1.1","v0.1.1-rc0","v0.1.0","helm-v0.1.0","v0.1.0-rc6","v0.1.0-rc5","v0.1.0-rc4","v0.1.0-rc3","v0.1.0-rc2","v0.1.0-rc1","v0.0.5","v0.0.5-rc2","v0.0.5-rc1","v0.0.4","v0.0.3","v0.0.2","0.2.0-rc1","v0.0.1","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-65834.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:N/I:N/A:H"}]}
