The EmbedPress WordPress plugin before 4.6.8 does not perform any capability or nonce check on an unauthenticated request that triggers a server-side, credential-bearing request to a third-party API and stores attacker-controlled cache entries, allowing unauthenticated attackers to consume the site owner's third-party API quota and write unbounded records into the site's database.

This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
