Security Findings2

Severity	Finding	Layer	Location
MEDIUM	Unpinned Rube MCP dependency The skill's manifest specifies a dependency on the 'rube' MCP without a version constraint (`"mcp": ["rube"]`). This means the skill will always use the latest available version of Rube, which could introduce breaking changes, new vulnerabilities, or malicious updates without explicit review or control. This poses a supply chain risk. Pin the 'rube' MCP dependency to a specific major or minor version (e.g., `"mcp": ["rube@1.2.3"]` or `"mcp": ["rube@^1.0"]`) in the manifest to ensure stability and allow for controlled updates, mitigating potential supply chain risks.

INFO	Broad tool execution capabilities via Rube MCP The skill leverages `RUBE_MULTI_EXECUTE_TOOL` and `RUBE_REMOTE_WORKBENCH` to automate Customgpt tasks. These Rube MCP tools are designed to execute arbitrary Composio tools, granting the agent broad capabilities across the Composio ecosystem. While necessary for an automation skill, users should be aware of the extensive actions an agent using this skill could perform, depending on the connected toolkits and permissions. No direct remediation for the skill itself, as this is its intended function. However, users deploying agents with this skill should implement robust access controls and monitoring for the Rube MCP and any connected toolkits to manage the scope of actions an agent can perform.
