A fix is available — apply it.

A flaw was found in the odh-model-controller. An authenticated user with permissions to create custom resources can exploit a vulnerability in the loadSecret function. This function improperly reads the Secret namespace from user-controlled input without validation. This allows an attacker to read sensitive API keys and cloud credentials from other namespaces, leading to information disclosure.
