CVE-2026-12517Fediverse Embeds < 1.5.8 - Unauthenticated SSRF via Site Info Endpoint

Does this affect you?

It affects Unknown Fediverse Embeds. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
