- Unnecessary Local Command-Execution Capability## Vulnerability Details **File Location**: `_meta.json:13`; `architecture.json:106` **Vulnerability Type**: Excessive command-execution permission **Risk Level**: High ### Vulnerable Code `_meta.json:13` ```json "tools": ["web_search", "web_fetch", "memory_search", "exec"] ``` `architecture.json:106` ```json "allowlist": ["web_search", "web_fetch", "read", "write", "exec"] ``` ### Technical Analysis The package grants the `exec` tool globally in its metadata and specifically to the business-opportunity analyst. The documented purpose of this agent is to retrieve public market information, perform technical analysis, and produce trading signals. These operations do not inherently require unrestricted local command execution. This violates the principle of least privilege. Because the analyst also consumes user input and untrusted external financial data, prompt injection or manipulated input could influence the arguments supplied to `exec`. The project does not define command restrictions, an executable allowlist, argument validation, shell isolation, or a constrained calculation interface. The metadata references `stock_analysis.py` and `scripts/stock_analysis.py`, but that script is absent from the audited package. Consequently, there is no bundled implementation that justifies or constrains the requested execution capability. ### Attack Path 1. An attacker supplies crafted content through a user request or a financial-data source consumed by the analyst. 2. The content attempts to convince the business-opportunity analyst that a local shell command is necessary to complete the analysis. 3. The analyst invokes the granted `exec` capability with attacker-influenced arguments. 4. The command executes with the privileges of the host agent process. 5. Depending on host sandboxing, the command could read or alter files, launch processes, or make additional network requests. No actual malicious command or con ...[truncated 580 chars]
- Remediation
- ## Remediation Suggestions 1. Remove `exec` from `_meta.json` and the business-opportunity analyst allowlist in `architecture.json`. 2. Perform ordinary market-data retrieval exclusively through `web_search` and `web_fetch`. 3. If local financial calculations are required, include the exact audited implementation in the package. 4. Expose calculations through a fixed-schema tool rather than a general shell. 5. Enforce an executable allowlist, fixed arguments, strict input validation, timeouts, resource limits, and network isolation. 6. Never concatenate user input or fetched market content into shell commands. 7. Fail closed if the referenced calculation script is missing or its integrity check fails.
