EmbedPress exposes unauthenticated blind SSRF
EmbedPress before 4.6.1 accepts caller-supplied URLs through unauthenticated endpoints and fetches them from the WordPress server without covering internal destinations that WordPress core URL validation misses. An unauthenticated attacker can therefore induce blind HTTP requests to internal hosts and services, although the response is not disclosed by the documented path. The public advisory does not disclose the endpoints, URL parameters, request function or omitted address classes.

This CVE was published Aug 04, 2026 and is one of 30 known issues for this plugin.
Update, patch or deactivate.
Update EmbedPress to 4.6.1 or later. Review outbound requests from the WordPress host and investigate internal services for unexpected requests originating from the site.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The EmbedPress WordPress plugin before 4.6.1 does not validate user-supplied URLs before making server-side requests through unauthenticated endpoints, allowing unauthenticated attackers to induce the site to send HTTP requests to internal hosts and services that WordPress core URL validation does not cover (a blind Server-Side Request Forgery).
