{"schema":"threatline.record/2","record":{"id":"CVE-2026-100848","aliases":["GHSA-4h6m-rrxm-7w3m"],"summary":"AzuraCast before 0.23.8 Server-Side Request Forgery via Remote Relay URL","details":"AzuraCast (Composer package azuracast/azuracast) before 0.23.8 validates a station's \"Remote Relay\" URL only for URL syntax and an http/https scheme (Utilities\\Urls::parseUserUrl, used by StationRemote::getUrlAsUri) and performs no host or IP address restriction. 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.","categories":["Unclassified"],"product":"AzuraCast","vendor":"AzuraCast","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100848","source_modified_at":"2026-09-28T16:38:16.249Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"AzuraCast","vendor":"AzuraCast","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"0.23.8"},{"version":"0.23.8","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100848","source_modified_at":"2026-09-28T16:38:16.249Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"AzuraCast","ecosystem":null},"version":"0.23.8","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00178,"percentile":0.0697,"score_date":"2026-10-23"},"published_at":"2026-09-27T01:28:42.329Z","modified_at":"2026-09-28T16:38:16.249Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100848","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T16:38:16.249Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100848","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/AzuraCast/AzuraCast/security/advisories/GHSA-4h6m-rrxm-7w3m","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/azuracast-before-0.23.8-server-side-request-forgery-via-remote-relay-url","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-28T16:25:12.283401Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-28T16:38:16.249Z","content_hash":"43233ae3e73617849d0a366e34110a5a4eccac6e2b41c2af77c9cd3f74e8b466"}}
