CVE-2023-2183: Grafana

Medium severity, CVSS 6.4. EPSS: 1% chance of exploitation in the next 30 days.

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.

Affected products

• Grafana Grafana: from 8.0.0, before 8.5.26 (fixed in 8.5.26); from 9.0.0, before 9.2.19 (fixed in 9.2.19); from 9.3.0, before 9.3.15 (fixed in 9.3.15); from 9.4.0, before 9.4.12 (fixed in 9.4.12); from 9.5.0, before 9.5.3 (fixed in 9.5.3)
