Description
WordPress Core is vulnerable to stored Cross-Site Scripting in versions up to, and including, 6.2, due to insufficient validation of the protocol in the response when processing oEmbed discovery. This makes it possible for authenticated attackers with contributor-level and above permissions to use a crafted oEmbed payload at a remote URL to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
