CVE-2026-42846
Received Received - Intake
Remote Code Execution in ClipBucket Video Sharing Platform

Publication date: 2026-06-11

Last updated on: 2026-06-11

Assigner: GitHub, Inc.

Description
ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.3 - #140, ClipBucket's Remote Play feature allows any authenticated user to add a video by importing an external URL as the source. Some shell commands are run with the URL as a parameter. The URL is concatenated directly into shell commands without escaping then executed, so any shell metacharacter in the URL is interpreted. This results in arbitrary command execution. This issue has been patched in version 5.5.3 - #140.

Executive Summary

This vulnerability exists in ClipBucket v5, an open source video sharing platform, specifically in its Remote Play feature prior to version 5.5.3 - #140. Authenticated users can add a video by importing an external URL as the source. However, the URL is directly concatenated into shell commands without proper escaping, allowing any shell metacharacters in the URL to be interpreted and executed. This leads to arbitrary command execution on the server.

Impact Analysis

This vulnerability can have severe impacts because it allows an authenticated user to execute arbitrary shell commands on the server hosting ClipBucket. This can lead to full system compromise, including unauthorized access, data theft, data modification, service disruption, or further exploitation of the affected system.

Mitigation Strategies

To mitigate this vulnerability, immediately upgrade ClipBucket to version 5.5.3 - #140 or later, where the issue has been patched.
