This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

Static analysis detected 534 potential security issues across shell scripts and documentation. After manual review, all findings are false positives from legitimate functionality: shell command examples in documentation (SETUP-CHECKLIST.md, TROUBLESHOOTING.md), standard API operations using curl/jq, config file access (~/.pexo/config) for credential storage, and network requests to official Pexo.ai endpoints. The skill is a legitimate video production tool with no malicious patterns detected.

references/SETUP-CHECKLIST.md:9-91 references/TROUBLESHOOTING.md:5-288

Documentation Contains Shell Command Examples

SETUP-CHECKLIST.md and TROUBLESHOOTING.md contain numerous shell command examples using backticks and command substitution. These are documentation examples showing users how to troubleshoot, not executable code. No security risk.

Clear documentation pattern - files are Markdown references with code blocks, not executable scripts. Commands are instructional examples for users.

Low

scripts/_common.sh:223-232 scripts/pexo-upload.sh:52-60 scripts/pexo-chat.sh:50-63

Standard Shell Utilities for File Operations

Scripts use standard shell commands (stat, basename, jq, curl) for legitimate file operations, JSON parsing, and HTTP requests. All commands use fixed arguments or validated user input. No command injection vectors detected.

Standard utility usage patterns - no user input directly injected without sanitization. File paths validated before use.

Low

scripts/_common.sh:3-8 SKILL.md:30-35

Config File Access for API Credentials

Script accesses ~/.pexo/config to read PEXO_API_KEY and PEXO_BASE_URL. This is the standard Unix pattern for storing user credentials. Config file is sourced with proper error handling.

Legitimate credential storage pattern following Unix conventions. File is user-owned with proper permissions documentation.

Low

SKILL.md:9-10 scripts/_common.sh:279

Network Requests to Official Pexo.ai Endpoints

All hardcoded URLs point to official Pexo.ai services (pexo.ai, pexo-assets.oss-us-east-1.aliyuncs.com). No third-party or suspicious endpoints detected. Network activity is for legitimate API communication.

All URLs verified as official service endpoints. No data exfiltration patterns detected.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Low

scripts/pexo-asset-get.sh:10

MD5 Hash Usage for Non-Security Purpose

One script uses MD5 hashing, but not for authentication or sensitive data. This is acceptable for non-security use cases like file deduplication or caching keys. No security impact.

MD5 used in utility context, not for security/crypto purposes. Acceptable use case.

Expert evidence
