| MEDIUM | Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/snail3d/clawd/security-scanner-skill/scripts/scanner.js:240 | |
| MEDIUM | Potential Command Injection via execSync The `scripts/scanner.js` file imports `execSync` from the `child_process` module. The skill's documentation (`SKILL.md`) describes a `--fix` option that suggests the skill can modify code files. If the implementation of this `--fix` functionality, or any other part of the skill, uses `execSync` with unsanitized user-provided input (such as file paths or arguments), it could lead to arbitrary command execution on the host system. While the specific usage of `execSync` is not fully visible in the truncated code, its presence combined with the documented file modification capability creates a credible exploit path for command injection. Review all usages of `execSync` and other `child_process` functions within `scripts/scanner.js`. Ensure that any user-controlled input, especially file paths or command arguments, is rigorously sanitized and validated before being passed to shell commands. Prefer using `child_process.spawn` with an explicit array of arguments to prevent shell interpretation, or use dedicated libraries for file manipulation instead of shell commands. | LLM | scripts/scanner.js:13 | |
| 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. | Dependencies | skills/snail3d/clawd/security-scanner-skill/package.json |
