Description

This security bulletin contains information about 1 vulnerability.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-19516)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: 7.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:L/SC:L/SI:N/SA:N]


The vulnerability allows a remote user to perform server-side request forgery and disclose sensitive information.

The vulnerability exists due to improper control of outbound request destinations in grafana_api_request when handling a supplied X-Grafana-URL header. A remote user can send a crafted request with a chosen header, HTTP method, path, and body to perform server-side request forgery and disclose sensitive information.

The issue can be used to reach internal, loopback, and link-local network services, including metadata endpoints.
