Noroxi assessment
Priority: Monitor (action score 20/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Grafana Grafana 10.4.17+security-01, 11.2.8+security-01, 11.3.5+security-01; Grafana Grafana Enterprise 10.4.17+security-01, 11.2.8+security-01, 11.3.5+security-01.
Low priority for now. Upgrade to Grafana Grafana 10.4.17+security-01, 11.2.8+security-01, 11.3.5+security-01; Grafana Grafana Enterprise 10.4.17+security-01, 11.2.8+security-01, 11.3.5+security-01 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
This vulnerability in Grafana's datasource proxy API allows authorization checks to be bypassed by adding an extra slash character in the URL path. Users with minimal permissions could gain unauthorized read access to GET endpoints in Alertmanager and Prometheus datasources. The issue primarily affects datasources that implement route-specific permissions, including Alertmanager and certain Prometheus-based datasources.
