A user holding only the Viewer role on an affected Grafana instance could send POST, PUT and DELETE requests through the proxy to the Loki rules API (/loki/api/v1/rules), allowing them to create, modify and delete Loki alerting rules. Because those rules are stored by Loki rather than by Grafana, the change took effect for every user of that Loki data source, not only for the Viewer who made the request.\n\nExploitation requires an authenticated Viewer account on the Grafana instance and a configured Loki data source; no other privileges are needed. Both Grafana OSS and Grafana Enterprise are affected. The defect is in Grafana's data source proxy; Loki itself is not vulnerable and does not need to be patched.","state":0,"publishedAt":"2026-10-15T14:02:00.146+00:00","modifiedAt":"2026-10-16T18:52:39.623+00:00","affected":[{"ecosystem":"Vendor product","name":"Grafana Enterprise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Grafana Enterprise\",\n                    \"vendor\": \"Grafana\",\n                    \"versions\": [\n                        {\n                            \"lessThanOrEqual\": \"11.5.10\",\n                            \"status\": \"affected\",\n                            \"version\": \"8.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"11.6.16\",\n                            \"status\": \"affected\",\n                            \"version\": \"11.6.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"12.1.10\",\n                            \"status\": \"affected\",\n                            \"version\": \"12.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"12.2.10\",\n                            \"status\": \"affected\",\n                            \"version\": \"12.2.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"12.3.8\",\n                            \"status\": \"affected\",\n                            \"version\": \"12.3.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"12.4.5\",\n                            \"status\": \"affected\",\n                            \"version\": \"12.4.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"13.0.3\",\n                            \"status\": \"affected\",\n                            \"version\": \"13.0.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Grafana OSS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Grafana OSS\",\n                    \"vendor\": \"Grafana\",\n                    \"versions\": [\n                        {\n                            \"lessThanOrEqual\": \"12.3.8\",\n                            \"status\": \"affected\",\n                            \"version\": \"12.3.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"12.4.5\",\n                            \"status\": \"affected\",\n                            \"version\": \"12.4.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"12.3.0\",\n                            \"status\": \"affected\",\n                            \"version\": \"8.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"13.0.3\",\n                            \"status\": \"affected\",\n                            \"version\": \"13.0.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","score":7.1,"severity":"HIGH"}],"references":["https://grafana.com/security/security-advisories/cve-2026-9703"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-9703","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-9703","identifiers":["CVE-2026-9703"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
