# CVE-2026-19130

> 5.8 MEDIUM

## Beschreibung

A flaw was found in the provider-credential-controller component of multicluster-engine (MCE). An attacker with specific permissions on the hub cluster, and knowledge of a prior credential value, could exploit an authorization bypass vulnerability. By manipulating `copiedFrom` labels, the attacker could intercept newly rotated provider credentials, leading to unauthorized information disclosure. This allows access to sensitive credentials that should otherwise be protected.
