Title
Fediverse Embeds < 1.5.8 - Unauthenticated SSRF via Site Info Endpoint
Summary
The Fediverse Embeds WordPress plugin before 1.5.8 does not validate the destination of the server-side request performed by an unauthenticated site-info endpoint before fetching it, allowing anonymous users (the gating nonce is exposed on public pages carrying an embed) to make the site request internal and private-network URLs and read back the parsed page metadata. This is a Server-Side Request Forgery.

Fediverse Embeds < 1.5.8 - Unauthenticated SSRF via Media Proxy
Summary

This results in a full-read Server-Side Request Forgery and open proxy.
