Security Findings5

Severity	Finding	Layer	Location
HIGH	API Key Leak via Unsafe Redirects The script uses `curl` with the `--location-trusted` flag. This flag forces `curl` to send the `Authorization` header (containing the sensitive API key) to any URL the server redirects to, including third-party domains. If the Moltbook API has an open redirect vulnerability or redirects to an untrusted domain, the agent's API key will be exfiltrated. Replace `--location-trusted` with `-L` (follow redirects) and ensure the API client does not automatically send credentials to different domains. If authentication is required on redirects, validate the redirect target domain before sending credentials.	Unknown	scripts/moltbook.sh:44
MEDIUM	Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated.	Unknown	/tmp/skillscan-clone-4bustasx/repo/scripts/moltbook.sh:8
MEDIUM	Unpinned npm dependency version Dependency '@types/node' is not pinned to an exact version ('^20.0.0'). Pin dependencies to exact versions to reduce drift and supply-chain risk.	Unknown	/tmp/skillscan-clone-4bustasx/repo/package.json
MEDIUM	API Path Traversal via Unsanitized Input User-supplied inputs such as `submolt` and `pool_id` are concatenated directly into API URL paths without URL encoding. This allows an attacker or confused agent to use path traversal characters (e.g., `../`) to access unintended API endpoints (e.g., accessing `/api/v1/admin` instead of `/api/v1/submolts/...`). Sanitize and URL-encode all user inputs used in URL path construction. For example, use `jq -sRr @uri` to encode variables before inserting them into the URL string, similar to how `cmd_discover` handles the query parameter.	Unknown	scripts/moltbook.sh:135
LOW	Node lockfile missing package.json is present but no lockfile was found (package-lock.json, pnpm-lock.yaml, or yarn.lock). Commit a lockfile for deterministic dependency resolution.	Unknown	/tmp/skillscan-clone-4bustasx/repo/package.json
