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.

CVE-2026-21720 (GCVE-0-2026-21720)

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.

CVE-2026-21721 (GCVE-0-2026-21721)

Vulnerability from cvelistv5 – Published: 2026-01-27 09:07 – Updated: 2026-01-28 04:55

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.
