From 0.13.0 until 0.13.7, hostnameRegexHandler.OnUpdate in internal/webhook/tenant/validation/hostname_regex.go reverses the new and old Tenant parameters and validates the previous AllowedHostnames.Regex instead of the submitted value. A cluster administrator can therefore store a malformed AllowedHostnames.Regex after the webhook accepts the update based on stale valid state. Subsequent Ingress creation or update reaches validate_hostnames.go, which evaluates the malformed pattern, ignores the regular-expression error, and treats every hostname as unmatched, blocking Ingress operations for the affected tenant until an administrator repairs the Tenant configuration. This issue is fixed in version 0.13.7.","state":0,"publishedAt":"2026-09-18T17:16:58.867+00:00","modifiedAt":"2026-09-24T21:25:27.05+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/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-f94q-w3w8-cj67"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61795","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-697"],"productCriteria":[],"sourceDates":{"published":"2026-09-18T17:16:58.867","lastModified":"2026-09-24T21:25:27.050"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
