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.","state":0,"publishedAt":"2026-09-18T16:26:18.669+00:00","modifiedAt":"2026-09-22T14:55:27.246+00:00","affected":[{"ecosystem":"Vendor product","name":"capsule","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"projectcapsule\",\n                    \"product\": \"capsule\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.13.0, < 0.13.7\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/projectcapsule/capsule/security/advisories/GHSA-gxjc-74v5-3vx3","https://github.com/projectcapsule/capsule/pull/1983","https://github.com/projectcapsule/capsule/commit/8d89d6865df6f41c7faa22fc9e807a57b01bfd0e","https://github.com/projectcapsule/capsule/releases/tag/v0.13.7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61794","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61794","identifiers":["CVE-2026-61794"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
