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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H","score":6.8},"cwes":["CWE-20","CWE-248"],"references":["https://github.com/projectcapsule/capsule/releases/tag/v0.13.8","https://github.com/projectcapsule/capsule/security/advisories/GHSA-68cj-mvg9-rgm2","https://github.com/projectcapsule/capsule/security/advisories/GHSA-68cj-mvg9-rgm2"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-65834","score":0.00322,"percentile":0.25022,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-68cj-mvg9-rgm2","url":"https://osv.dev/vulnerability/GHSA-68cj-mvg9-rgm2","summary":"Capsule: CapsuleConfiguration NodeMetadata regex fields lack webhook validation, allowing MustCompile panic on all Node admission requests","modified":"2026-08-18T15:10:36.744194855Z","packages":[{"ecosystem":"Go","name":"github.com/projectcapsule/capsule","purl":"pkg:golang/github.com/projectcapsule/capsule","ranges":["<0.13.8"],"fixed":["0.13.8"]}]},{"id":"GO-2026-6155","url":"https://osv.dev/vulnerability/GO-2026-6155","summary":"Capsule: CapsuleConfiguration NodeMetadata regex fields lack webhook validation, allowing MustCompile panic on all Node admission requests in github.com/projectcapsule/capsule","modified":"2026-08-18T15:00:16.143071626Z","packages":[{"ecosystem":"Go","name":"github.com/projectcapsule/capsule","purl":"pkg:golang/github.com/projectcapsule/capsule","ranges":["<0.13.8"],"fixed":["0.13.8"]}]}],"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).
