CVE-2026-4357 Sep 02, 14:16 CRITICAL POC CERT-EU Act Now

Unrestricted file upload in the Embed HTML5 Game WordPress plugin (versions through 1.3) lets unauthenticated attackers upload arbitrary files - including PHP scripts - because the plugin neither restricts who may upload nor validates file type, enabling planting of PHP backdoors and full remote code execution. WPScan reports the flaw with a publicly available exploit, and the CVSS 10.0 rating reflects unauthenticated network exploitation with complete impact. No CISA KEV listing exists, but the combination of PR:N and a public PoC makes opportunistic scanning likely.
