Grafana vulnerable to Cross-site Scripting

The team sync HTTP API in Grafana Enterprise 7.4.x before 7.4.5 has an Incorrect Access Control issue. On Grafana instances using an external authentication service, this vulnerability allows any authenticated user to add external groups to existing teams. This can be used to grant a user team permissions that the user isn't supposed to have.

Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service.

The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers.

Grafana Data source and plugin proxy endpoints could leak the authentication cookie to some destination plugins

Grafana Incorrect Privilege Assignment vulnerability

A time-of-create-to-time-of-use (TOCTOU) vulnerability lets recently deleted-then-recreated data sources be re-deleted without permission to do so. This requires several very stringent conditions to be met: - The attacker must have admin access to the specific datasource prior to its first deletion. - Upon deletion, all steps within the attack must happen within the next 30 seconds and on the same pod of Grafana. - The attacker must delete the datasource, then someone must recreate it. - The new datasource must not have the attacker as an admin. - The new datasource must have the same UID as the prior datasource. These are randomised by default. - The datasource can now be re-deleted by the attacker. - Once 30 seconds are up, the attack is spent and cannot be repeated. - No datasource with any other UID can be attacked.

Grafana Race condition allowing privilege escalation

Grafana 8.4.3 allows reading files via (for example) a /dashboard/snapshot/%7B%7Bconstructor.constructor'/.. /.. /.. /.. /.. /.. /.. /.. /etc/passwd URI.
