CVE-2023-2183

grafana: missing access control allows test alerts by underprivileged user

Published Jun 6, 2023 CVSS 3.1 · 4.1 Medium EPSS 1.0% KEV · Not listed
Description
Grafana is an open-source platform for monitoring and observability.

The option to send a test alert is not available from the user panel UI for users having the Viewer role. It is still possible for a user with the Viewer role to send a test alert using the API as the API does not check access to this function.

This might enable malicious users to abuse the functionality by sending multiple alert messages to e-mail and Slack, spamming users, prepare Phishing attack or block SMTP server.

Users may upgrade to version 9.5.3, 9.4.12, 9.3.15, 9.2.19 and 8.5.26 to receive a fix.
