MEDIUM
Base64 encode and send
L258

Detects base64 encoding of content followed by transmission

base64 encode + curl
FIX

Block patterns that base64-encode data and immediately transmit it. If base64 encoding is needed, ensure the encoded data does not contain secrets and destinations are allowlisted.

FP?

Likely FP if base64 encoding is used for legitimate purposes like encoding images for display or constructing data URIs, with no network transmission.

LOW
Runtime URL controlling behavior
L82

Detects URLs fetched at runtime that control or influence agent behavior without pinning

read the API address from environment variable, with `http:// + Instructions
FIX

Avoid loading configuration or behavior-controlling content from runtime URLs. Bundle required configurations locally or pin remote config to versioned, integrity-verified endpoints.

FP?

Likely FP if the URL in the match is a documentation link or example URL (e.g., example.com) rather than an actual runtime-fetched configuration endpoint.

LOW
Non-localhost remote MCP server URL
L89

Detects MCP server configurations connecting to non-localhost remote URLs

"url": "https://example.com"
FIX

Change the MCP server URL to localhost or a trusted internal endpoint. If a remote server is required, verify the domain ownership and use HTTPS with certificate validation.

FP?

Likely FP if the URL points to example.com, a documentation domain, or a well-known SaaS API endpoint (e.g., api.openai.com).

LOW
Non-localhost remote MCP server URL
L140

Detects MCP server configurations connecting to non-localhost remote URLs

"url": "https://example.com"
FIX

Change the MCP server URL to localhost or a trusted internal endpoint. If a remote server is required, verify the domain ownership and use HTTPS with certificate validation.

FP?

Likely FP if the URL points to example.com, a documentation domain, or a well-known SaaS API endpoint (e.g., api.openai.com).

LOW
Non-localhost remote MCP server URL
L179

Detects MCP server configurations connecting to non-localhost remote URLs

"url": "https://example.com/search"
FIX

Change the MCP server URL to localhost or a trusted internal endpoint. If a remote server is required, verify the domain ownership and use HTTPS with certificate validation.

FP?

Likely FP if the URL points to example.com, a documentation domain, or a well-known SaaS API endpoint (e.g., api.openai.com).

LOW
Non-localhost remote MCP server URL
L341

Detects MCP server configurations connecting to non-localhost remote URLs

"url": "https://example.com/login"
FIX

Change the MCP server URL to localhost or a trusted internal endpoint. If a remote server is required, verify the domain ownership and use HTTPS with certificate validation.

FP?

Likely FP if the URL points to example.com, a documentation domain, or a well-known SaaS API endpoint (e.g., api.openai.com).

LOW
Non-localhost remote MCP server URL
L402

Detects MCP server configurations connecting to non-localhost remote URLs

"url": "https://example.com/form"
FIX

Change the MCP server URL to localhost or a trusted internal endpoint. If a remote server is required, verify the domain ownership and use HTTPS with certificate validation.
