Upgrade phanan/koel to version 9.7.1 or higher.
Overview
phanan/koel is a personal audio streaming service.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the isPublicHost process. An attacker can access internal resources and retrieve sensitive information by supplying a specially crafted podcast enclosure URL that resolves to an IPv6 transition address embedding a private or reserved IPv4 address. This is only exploitable if the server is deployed in an environment with NAT64 or 6to4/dual-stack routing enabled.
