{"id":"CVE-2026-61794","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-61794","summary":"Capsule is a multi-tenancy and policy-based framework for Kubernetes. From 0.13.0 until 0.13.7, the Tenant update validation in internal/webhook/tenant/validation/forbidden_annotations_regex.go…","details":"Capsule is a multi-tenancy and policy-based framework for Kubernetes. From 0.13.0 until 0.13.7, the Tenant update validation in internal/webhook/tenant/validation/forbidden_annotations_regex.go compiles ForbiddenLabels.Regex for both the labels and annotations checks instead of validating ForbiddenAnnotations.Regex. An administrator who can update a Tenant can therefore persist a malformed ForbiddenAnnotations.Regex while leaving the labels expression valid. Namespace creation or update later passes the stored expression through pkg/api/forbidden_list.go, where regexp.MustCompile can panic during forbidden metadata validation and deny namespace operations for the affected tenant. This issue is fixed in version 0.13.7.","published":"2026-09-18T17:16:58.700","modified":"2026-09-18T17:16:58.700","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/projectcapsule/capsule/commit/8d89d6865df6f41c7faa22fc9e807a57b01bfd0e","label":"projectcapsule/capsule@8d89d68"},"references":[{"type":"WEB","url":"https://github.com/projectcapsule/capsule/commit/8d89d6865df6f41c7faa22fc9e807a57b01bfd0e"},{"type":"WEB","url":"https://github.com/projectcapsule/capsule/pull/1983"},{"type":"WEB","url":"https://github.com/projectcapsule/capsule/releases/tag/v0.13.7"},{"type":"WEB","url":"https://github.com/projectcapsule/capsule/security/advisories/GHSA-gxjc-74v5-3vx3"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T17:16:58.700"}}
