Summary

CVE-2026-41304 is a high-severity Command Injection (CWE-77) vulnerability in Wwbn Avideo. Its CVSS base score is 8.9 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 19% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

WWBN AVideo is an open source video platform that contains a command injection vulnerability in versions 29.0 and below. The flaw resides in the cloneServer.json.php endpoint of the CloneSite plugin, which constructs shell commands by directly concatenating unsanitized user input from the url parameter into a wget command executed via exec(). This allows an attacker to break out of the intended URL context using shell metacharacters such as semicolons, resulting in arbitrary command execution on the server. The issue is tracked under CWE-77 and carries a CVSS 4.0 score of 8.9.

Unauthenticated remote attackers can exploit the endpoint over the network without authentication or user interaction to achieve full remote code execution, gaining the ability to run arbitrary shell commands on the affected server.

The vulnerability is fixed in commit 473c609fc2defdea8b937b00e86ce88eba1f15bb, with details published in the associated GitHub security advisory GHSA-xr6f-h4x7-r6qp.

The EPSS score reached a peak of 0.0131 from a current value of 0.0065, indicating limited but observable post-disclosure interest.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 Information Input Validation good match

Input validation directly stops construction of commands from untrusted data containing special elements.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches command-injection vulnerabilities before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

A.8.31 Separation of development, test and production environments none match
none

Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
