Security audit reveals high-severity credential handling concerns. The skill accesses API keys via environment variables and stores them in plaintext files at ~/.shareone_credentials without encryption. API keys are passed as command-line arguments, exposing them in process lists. The skill connects exclusively to shareone.sudoprivacy.com for file hosting. While no malicious intent was found, the credential storage patterns present elevated risk that requires user awareness.

High
scripts/check_api_key.js:14-17scripts/save_api_key.js:11-12scripts/create_guest_key.js:16-17
Plaintext Credential Storage
API keys are stored in plaintext at ~/.shareone_credentials without encryption. Any user with filesystem access can read stored credentials.
Direct evidence found in code: fs.writeFileSync saves plaintext JSON with api_key to homedir without encryption
Medium
scripts/save_api_key.js:5-12
Unvalidated Credential Acceptance
The skill accepts user-provided API keys and saves them to disk without validation. Attackers could trick users into providing credential strings.
Skill instructions explicitly prompt users to provide API keys which are then saved to disk without verification
Medium
SKILL.md:47-48SKILL.md:116-117SKILL.md:134
External Command Execution via Shell
Node.js child_process is used to execute shell commands (node scripts/...) for file operations. Arguments are sourced from environment variables.
Documentation shows bash commands with $SHAREONE_API_KEY being executed, though arguments are from env vars not user input

Risk findings

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

Confirmed security concerns (3)

RISK-001 High
scripts/upload_page.js:14scripts/shareone_upload.js:145-146
API Key Exposed via Command-Line Arguments
API keys are passed as CLI arguments to Node.js scripts (--api-key parameter), making them visible in process listings and shell history.
CLI argument parsing shows apiKey is passed via --api-key flag, visible in process.argv and process listings
RISK-002 Low
SKILL.md:74SKILL.md:77
Hardcoded Domain in SKILL.md
The shareone.sudoprivacy.com domain is hardcoded throughout documentation. While not inherently insecure, makes tracking difficult.
Domain is hardcoded but appears intentional for the service integration
RISK-003 Low
SKILL.md:40SKILL.md:158
High Entropy Strings Detected
Static analysis detected high entropy strings in SKILL.md. Upon review, these are base64-encoded URLs or example filenames, not malicious payloads.
Entropy detection flagged example URLs and filenames, which are legitimate documentation content
