The advisory

The FV Flowplayer Video Player WordPress plugin before 7.5.55.7212 does not properly validate a user-supplied URL before performing a server-side fetch, and an existing host-based restriction fails to cover all cases, allowing users with Contributor-level access and above to perform Server-Side Request Forgery (SSRF) attacks. The impact is limited to a semi-blind oracle: the server's fetch reveals whether an internal resource responds and its HTTP status, but the resource's contents are not returned to the attacker.
