{"cve":"CVE-2026-61794","nvd":{"published":"2026-09-18T17:16:58.700","modified":"2026-09-24T21:25:27.050","status":"Deferred","description":"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.","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"],"references":["https://github.com/projectcapsule/capsule/commit/8d89d6865df6f41c7faa22fc9e807a57b01bfd0e","https://github.com/projectcapsule/capsule/pull/1983","https://github.com/projectcapsule/capsule/releases/tag/v0.13.7","https://github.com/projectcapsule/capsule/security/advisories/GHSA-gxjc-74v5-3vx3","https://github.com/projectcapsule/capsule/security/advisories/GHSA-gxjc-74v5-3vx3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-61794","score":0.00587,"percentile":0.48104,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gxjc-74v5-3vx3","url":"https://osv.dev/vulnerability/GHSA-gxjc-74v5-3vx3","summary":"Capsule: Malformed ForbiddenAnnotations.Regex can bypass Tenant validation and trigger namespace admission panic","modified":"2026-09-28T17:11:19.835452014Z","packages":[{"ecosystem":"Go","name":"github.com/projectcapsule/capsule","purl":"pkg:golang/github.com/projectcapsule/capsule","ranges":[">=0.13.0 <0.13.7"],"fixed":["0.13.7"]}]},{"id":"GO-2026-6521","url":"https://osv.dev/vulnerability/GO-2026-6521","summary":"Capsule: Malformed ForbiddenAnnotations.Regex can bypass Tenant validation and trigger namespace admission panic in github.com/projectcapsule/capsule","modified":"2026-09-28T17:00:17.353246800Z","packages":[{"ecosystem":"Go","name":"github.com/projectcapsule/capsule","purl":"pkg:golang/github.com/projectcapsule/capsule","ranges":[">=0.13.0 <0.13.7"],"fixed":["0.13.7"]}]}],"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).
