Vulnerability Type: Violation of least-privilege principles
Risk Level: MediumRelevant snippet, translated into English from the source-language table row:
markdown | Insufficient permissions | The current user lacks read/write permission | Check the file permissions and run as administrator |Technical Analysis
The troubleshooting guidance recommends running the process as an administrator whenever a permission error occurs. It does not identify the specific resource requiring access, restrict elevation to a narrowly scoped trusted operation, or require validation of commands and input before elevation.
This is particularly risky because the Skill declares command-execution capability and is designed to process user-provided files, paths, data sources, and instructions. If generated commands, analysis code, file contents, or user-controlled parameters are unsafe, rerunning the workflow as an administrator gives that unsafe operation substantially broader access.
The recommendation therefore breaks the principle of least privilege. A permission error should be addressed by determining which resource requires access and granting only the minimum necessary permission, rather than elevating the entire Agent or analysis session.
Attack Path
- An attacker supplies a malicious or untrusted dataset, file path, analysis instruction, or command parameter.
- Processing triggers a permission error while accessing a protected resource.
- The troubleshooting instructions recommend rerunning the operation as an administrator.
- The user or Agent elevates the complete workflow without isolating or reviewing the affected operation.
- Attacker-controlled input or generated code executes with elevated privileges.
- The operation can access or modify resources that were unavailable to the original process.

Remediation Suggestions
- Remove the general recommendation to run the Agent or workflow as an administrator.
- Instruct users to identify the exact file, directory, socket, or service causing the permission failure.
- Grant only the minimum required read or write permission to that specific resource and only for the required account.
- Run generated analysis code and command execution inside a sandbox or container under an unprivileged service account.
- Require explicit review of commands, paths, and user-controlled parameters before any privileged operation.
- If elevation is unavoidable, isolate it to a fixed, trusted helper operation with an allowlist of permitted actions; never elevate arbitrary generated commands.
- Reject path traversal, symbolic-link redirection, shell metacharacters, and access to protected system locations when processing user-provided paths.
- Record privileged attempts in an audit log and fail safely instead of automatically retrying with broader permissions.
