CVE-2026-100105 · Severity: high · CVSS 7.7 · Published 2026-10-28

Grafana is an observability platform that manages alert notifications through contact points. A user with limited permissions to edit contact points can circumvent access controls by switching to a legacy schema version, allowing them to modify protected settings like notification URLs and steal stored credentials. This enables redirection of critical alerts to attacker-controlled systems.

## Technical details

An incorrect authorization check in Grafana's contact point management allows users with edit permissions but restricted access to protected fields to bypass these restrictions by downgrading the integration to a legacy schema version. The vulnerability affects the handling of contact point modifications and enables attackers to change destination URLs and expose stored API credentials. The attack requires authentication and valid edit permissions on contact points.
