Grafana — свободная программная система визуализации данных, ориентированная на данные систем ИТ-мониторинга.

A request to the Grafana plugin resources endpoint can cause unbounded memory allocation by reading the entire request body into memory. An authenticated user can exploit this to trigger an out-of-memory condition, potentially causing a denial of service.

A race condition in Grafana Live allows authenticated users with Viewer role to trigger a server crash by sending concurrent requests that cause a fatal map access error. This results in complete service unavailability requiring restart of the Grafana server.

Any Editor could delete any snapshot, even if they have no access to read or write them.

An Editor can overwrite a dashboard not owned by them to acquire admin on that specific dashboard. The user must have write access to the dashboard to escalate privilege.

When a user's access to mint tokens for a service account is revoked, it is sometimes still possible to do so for a few seconds after the event. The user will eventually lose access to do this.

Using the $__timeGroup macro, one can achieve an OOM by overloading the server. This requires a SQL datasource. If the server is set up to auto-restart, the impact is minimal or non-existent, as the attack can take upwards of half an hour to crash the server.

When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses. Addresses specifying a mask explicitly are not affected; to mitigate easily, add the desired mask (usually /128) to the addresses. Only auth proxy is affected; Okta, SAML, LDAP, etc are unaffected here.

A vulnerability in SQL Expressions allows an authenticated attacker to read arbitrary files from the Grafana server's filesystem. Only instances with the sqlExpressions feature toggle enabled are vulnerable.
