RHSA-2026:54178 PUBLISHED CVSS 7.099999904632568 HIGH

Record from redhat · Published August 12, 2026

A flaw was found in Grafana. An unauthenticated attacker can repeatedly access the OAuth login route with unique values. This can lead to unbounded memory growth, eventually exhausting system memory and causing the Grafana instance to crash. This results in a denial of service for legitimate users.
