A tenant with HelmRelease create permissions can exploit this vulnerability by manipulating the `secretRef.Namespace` field. This allows the `GetSecret()` function in the HelmRelease controller to fetch sensitive credentials from any namespace, which are then sent to an attacker-controlled Helm repository. This can lead to the exfiltration of credentials from arbitrary namespace Secrets, resulting in information disclosure.","published":"2026-08-20T21:17:09.270","modified":"2026-08-20T21:17:09.270","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-73137"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2514223"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-20T21:17:09.270"}}
