grafana: Grafana: Session takeover via Auth Proxy cache key collision

On instances using Auth Proxy header authentication auth.proxy with identity caching enabled syncttl 0, two distinct user identities could produce the same cache key. An authenticated low-privileged user able to influence their own forwarded identity attributes could be served a higher-privileged...

BIT-GRAFANA-2026-14199 Session takeover via Auth Proxy cache key collision

Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled syncttl 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...
