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… (CVE-2026-100848)
AzuraCast versions before 0.23.8 have a vulnerability where the 'Remote Relay' URL is only validated for syntax and scheme, without host or IP restrictions. This allows users with station-scoped RemoteRelays permission to set URLs pointing to internal or sensitive addresses, causing the server to make repeated HTTP requests to these addresses. This results in server-side request forgery (SSRF). No patch is currently available for this issue.

Technical Summary
AzuraCast (Composer package azuracast/azuracast) prior to version 0.23.8 validates a station's 'Remote Relay' URL only for URL syntax and http/https scheme, without restricting host or IP addresses. A user with the station-scoped RemoteRelays permission can configure a Remote Relay URL targeting loopback, private network, or cloud metadata service addresses (e.g., http://127.0.0.1:<port>/ or http://169.254.169.254/latest/meta-data/). AzuraCast's periodic background Now Playing sync process automatically and repeatedly issues HTTP requests to the specified URL, enabling server-side request forgery (CWE-918) against internal resources. The vulnerability is identified as CVE-2026-100848 with a CVSS 3.1 score of 7.1 (high severity). As of the advisory date, no patched version is available.
Potential Impact
An attacker with station-scoped RemoteRelays permission can exploit this vulnerability to cause the AzuraCast server to make HTTP requests to internal or sensitive network addresses. This can lead to unauthorized access or information disclosure from internal services, such as cloud metadata endpoints. The impact includes high confidentiality loss but limited integrity and availability impact. There is no indication of active exploitation in the wild.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should exercise caution by restricting permissions to trusted users only and monitoring configurations for suspicious Remote Relay URLs. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
