CVE-2026-21722 (GCVE-0-2026-21722)

Title
Public Dashboards time range restriction on annotations can be bypassed
Summary
Public dashboards with annotations enabled did not limit their annotation timerange to the locked timerange of the public dashboard. This means one could read the entire history of annotations visible on the specific dashboard, even those outside the locked timerange.
This did not leak any annotations that would not otherwise be visible on the public dashboard.

Title
XSS in Grafana Explore stack trace
Summary
Stack traces in Grafana's Explore Traces view can be rendered as raw HTML, and thus inject malicious JavaScript in the browser. This would require malicious JavaScript to be entered into the stack trace field.
Only datasources with the Jaeger HTTP API appear to be affected; Jaeger gRPC and Tempo do not appear affected whatsoever.

Title
Dashboard Permissions Scope Bypass Enables Cross‑Dashboard Privilege Escalation
Summary
The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.

Title
Unauthenticated DoS: avatar cache leaks goroutines when /avatar/:hash requests time out
Summary
Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems.

Title
XSS in Grafana Explore stack trace
Summary
Stack traces in Grafana's Explore Traces view can be rendered as raw HTML, and thus inject malicious JavaScript in the browser. This would require malicious JavaScript to be entered into the stack trace field.
Only datasources with the Jaeger HTTP API appear to be affected; Jaeger gRPC and Tempo do not appear affected whatsoever.

Title
Public Dashboards time range restriction on annotations can be bypassed
Summary
Public dashboards with annotations enabled did not limit their annotation timerange to the locked timerange of the public dashboard. This means one could read the entire history of annotations visible on the specific dashboard, even those outside the locked timerange.
This did not leak any annotations that would not otherwise be visible on the public dashboard.

Title
Dashboard Permissions Scope Bypass Enables Cross‑Dashboard Privilege Escalation
Summary
The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.

Title
Unauthenticated DoS: avatar cache leaks goroutines when /avatar/:hash requests time out
Summary
Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems.

If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems."
