CVE-2023-2183
Grafana has Broken Access Control in Alert manager: Viewer can send test alerts
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.
