A user holding only the station-scoped RemoteRelays permission can therefore set a Remote Relay URL pointing at loopback, private-network, or cloud-metadata addresses (e.g. http://127.0.0.1:<port>/ or http://169.254.169.254/latest/meta-data/), and AzuraCast's periodic background Now Playing sync (AbstractRemote::getNowPlayingAsync) will automatically and repeatedly issue HTTP requests to that address, resulting in server-side request forgery against internal resources. This affects the main branch as of commit bcf8754eef3a268ad82c3db4d81f7920c3c28b56 (2026-07-31); no patched version is available at the time of the advisory.","state":0,"publishedAt":"2026-09-27T01:28:42.329+00:00","modifiedAt":"2026-09-28T16:38:16.249+00:00","affected":[{"ecosystem":"Vendor product","name":"AzuraCast","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"AzuraCast\",\n                    \"product\": \"AzuraCast\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.23.8\"\n                        },\n                        {\n                            \"version\": \"0.23.8\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/AzuraCast/AzuraCast/security/advisories/GHSA-4h6m-rrxm-7w3m","https://www.vulncheck.com/advisories/azuracast-before-0.23.8-server-side-request-forgery-via-remote-relay-url"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100848","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100848","identifiers":["CVE-2026-100848"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
