Official Description

WWBN AVideo is an open source video platform. In versions 29.0 and below, 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. Commit 473c609fc2defdea8b937b00e86ce88eba1f15bb contains a fix.

Technical Analysis

CVE-2026-41304 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
