   Grafana Mimir's Alertmanager rejects tenant-supplied receiver configurations that reference local files, but the check did not cover two HTTP client settings: http_headers.<name>.files and basic_auth.username_file. A tenant permitted to upload an Alertmanager configuration could point these fields at any file readable by the Alertmanager process. When a notification was sent, Alertmanager read the file and put its contents in a header of the outgoing request.

   A user with read access to Grafana's server logs, or to a log store they are shipped to, can recover the OAuth and OIDC access, refresh and ID tokens of users who sign in through the Generic OAuth, Google or GitLab providers. Grafana writes these tokens to its logs unredacted when an access or ID token is not a valid JWT, when the ID token is missing (at debug level) or is not a string (exposure of sensitive information in log files). The exposure is bounded by the scopes granted to the configured OAuth client.

    Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when extracting plugin archives. A crafted plugin archive can chain relative symbolic link entries to escape the plugin installation directory, writing arbitrary files and an executable backend binary outside that directory. The dropped executable runs with the privileges of the Grafana server process, resulting in remote code execution. Plugin archives are extracted before their signature is verified, so a valid plugin signature does not prevent the write. An operator can therefore be affected by installing a plugin that
