What is CVE-2026-12517?

The Fediverse Embeds WordPress plugin, prior to version 1.5.8, contains a vulnerability that permits unauthenticated users to conduct Server-Side Request Forgery (SSRF) attacks. Through a compromised site-info endpoint, attackers can send requests to internal and private-network URLs, thereby obtaining sensitive metadata from the parsed pages. This flaw arises due to insufficient validation of the server-side request destination, which can lead to unauthorized information disclosure. Website administrators are advised to upgrade to the latest version to mitigate this risk.

Affected Version(s)

Fediverse Embeds 0 < 1.5.8

Exploit Proof of Concept (PoC)
