CyberRota Analysis
AI-GeneratedThe Grafana Alloy component in Kubernetes is vulnerable due to its handling of ServiceMonitor resources, allowing users with write access to specify arbitrary local files via bearerTokenFile. This can lead to the disclosure of sensitive files, including the Kubernetes service account token, potentially granting attackers elevated permissions within the Kubernetes environment. Organizations using Grafana Alloy should prioritize addressing this vulnerability, especially those with users who can create or modify ServiceMonitor resources.

Original NVD Description
Grafana Alloy’s prometheus.operator.servicemonitors component allows a user who can create or modify ServiceMonitor resources in a watched namespace to specify an arbitrary local file through bearerTokenFile. Alloy reads the file and sends its contents as a bearer token to an attacker-controlled scrape endpoint. This may disclose files accessible to the Alloy process, including its projected Kubernetes service account token, potentially granting the attacker Alloy’s Kubernetes permissions. Exploitation requires ServiceMonitor write access and lower privileges than Alloy’s service account.
