GHSA-7j2f-6h2r-6cqc: phanan/koel (CVE-2026-47260)

Package	Ecosystem	Affected	Fixed in
phanan/koel	Packagist	<9.3.5	9.3.5

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-7j2f-6h2r-6cqc concerns the Koel music server (Packagist phanan/koel) in versions before 9.3.5. Episode enclosure URLs parsed from podcast RSS feeds are stored without the SSRF checks applied to the feed URL, so when an episode is played the server fetches the full response from that URL and streams it back. An authenticated user, including one on the Community edition, could subscribe to a malicious feed to read internal or cloud metadata responses. Upgrade to version 9.3.5 or later, which is the listed fixed version.
