CVE-2023-34842Network attack vector

Unauthenticated code execution via crafted POST request

Published Jul 31, 2023 · Updated Jul 9, 2026

Remote code execution in DedeCMS 5.7.109 and earlier allows remote attackers to run arbitrary code via a crafted POST request to /dede/tpl.php. The public record identifies the affected endpoint but does not disclose which parameter or code path turns request data into executable code. No authentication or user interaction is required, and successful exploitation executes attacker-chosen code in the web application's context.
