How to fix?

Upgrade Minimos:latest grafana-13.2 to version 13.2.1-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grafana-13.2 package and not the grafana-13.2 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).
