Openclaw Skill Cutmv Video Tool

Security checks across malware telemetry and agentic risk

Overview

This appears to be a legitimate FFmpeg video tool, but it needs review because unsafe metadata parsing could execute code and outputs overwrite files by default.

Install only if you are comfortable reviewing or patching the code first. Avoid running it on untrusted media until eval is replaced with strict numeric fraction parsing, use explicit output paths in non-sensitive folders, and assume existing files at output paths may be overwritten.

Missing User Warnings

Medium
Confidence
84% confidence
Finding
The wrapper forces FFmpeg overwrite mode with '-y' for all operations, which can silently destroy existing files if a user supplies an existing path or a path is constructed incorrectly. In an agent or automated workflow context, that increases the likelihood of unintended data loss because no confirmation barrier exists.
