Trust Assessment
Briefing Room received a trust score of 19/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 4 findings: 2 critical, 1 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Sensitive environment variable access: $HOME.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Static Code Analysis layer scored lowest at 63/100, indicating areas for improvement.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/matusvojtek/briefing-room/scripts/briefing.sh:172 | |
| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/matusvojtek/briefing-room/scripts/briefing.sh:172 | |
| HIGH | Command Injection via Unsanitized Configuration Values The `scripts/briefing.sh` script is vulnerable to command injection. Configuration values for `trends.regions` and `webtrends.regions` are read from `~/.briefing-room/config.json` and directly used in shell commands (`xargs`, `awk`) without proper sanitization. An attacker who can modify the `config.json` file (e.g., via `scripts/config.py set` or another compromised skill) can inject arbitrary shell commands that will be executed when the agent runs `briefing.sh trends` or `briefing.sh webtrends`. Implement strict input validation for `trends.regions` and `webtrends.regions` in `scripts/config.py` to ensure they only contain allowed characters (e.g., alphanumeric, hyphens, commas) and no shell metacharacters. Additionally, in `scripts/briefing.sh`, sanitize or quote variables like `$slug` and `$label` when they are passed to shell commands like `xargs` or `awk` to prevent their content from being interpreted as commands. For example, use `printf %s "$slug" | xargs` instead of `echo "$slug" | xargs` to prevent shell interpretation of `$slug`. | LLM | scripts/briefing.sh:78 | |
| 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. | Static | skills/matusvojtek/briefing-room/scripts/briefing.sh:17 |
