Upgrade github.com/grafana/grafana/pkg/api to version 12.4.0 or higher.
Overview
github.com/grafana/grafana/pkg/api is an open and composable observability and data visualization platform.
Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition through a time-of-check-to-time-of-use condition in the datasource deletion process. An attacker can cause unauthorized deletion of a newly recreated datasource by exploiting a race condition after deletion and before permission checks are updated.
Note: This is only exploitable if the attacker previously had admin access to the datasource, deletes it, the datasource is recreated within 30 seconds on the same pod with the same UID but without the attacker as admin, and all actions occur within this short window.
