Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

All five static findings are false positives: the backticks are Markdown formatting, and the hardcoded URL is a documentation link. The skill still introduces a medium-risk capability because generated backend code can send requests to arbitrary URLs without documented validation or allowlisting.

Confirmed security concerns (1)

RISK-001 Medium

SKILL.md:41-44 SKILL.md:58-59

Unrestricted Backend HTTP Targets

The documented helpers accept arbitrary URL text, and the GET example forwards a URL without validation. Generated integrations could enable SSRF or unintended data transmission.

The function signatures and example directly accept URL text. Exploitability depends on whether generated callers use untrusted input.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

FIX-001
Medium
Arbitrary backend outcall targets

Document URL validation and host allowlisting. Warn authors not to pass user-controlled URLs to the outcall helpers.
FIX-002
Medium
Potential sensitive data disclosure

Add guidance for protecting credentials and request data. Secrets should only be sent to trusted, approved endpoints.
