CVE-2026-47260Public exploitNetwork attack vector

Internal response disclosure via unvalidated podcast enclosures

Published Jun 12, 2026 · Updated Jun 12, 2026

SSRF in Koel before 9.3.5 allows remote authenticated users to read internal HTTP responses through crafted podcast episode enclosures. PodcastService stores RSS enclosure URLs without SafeUrl validation, and EpisodePlayable passes each stored URL to Http::sink()->get() before streaming the full response. Any registered Community-edition account can trigger the fetch, exposing HTTP services reachable from the Koel server without altering them.
