CVE-2026-41304: WWBN AVideo: RCE cause by clonesite plugin

April 16, 2026 (updated April 24, 2026)

The cloneServer.json.php endpoint in the CloneSite plugin constructs shell commands using user-controlled input (url parameter) without proper sanitization. The input is directly concatenated into a wget command executed via exec(), allowing command injection.

An attacker can inject arbitrary shell commands by breaking out of the intended URL context using shell metacharacters (e.g., ;). This leads to Remote Code Execution (RCE) on the server.
