Loading the registry…
Review APIs for security vulnerabilities against the OWASP API Security Top 10 (2023). Accepts OpenAPI/Swagger specs, API code, or both. Analyzes authentication, authorization, data exposure, rate limiting, input validation, and business logic flaws. Generates a formal API Security Report with per-endpoint findings and remediation guidance. Use this skill whenever the user asks to review an API for security, audit an OpenAPI spec, check REST/GraphQL endpoints for vulnerabilities, assess API auth patterns, or validate API design against security best practices. Also trigger on: 'API security review', 'OWASP API Top 10', 'audit OpenAPI/Swagger spec', 'endpoint/REST/GraphQL security', 'API pentest review', or any request to find security issues in API definitions or implementations.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
1 critical finding reported by cisco-skill-scanner. The composite score alone does not reflect this — read the per-scanner reports below.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'cloudyrion/cloudyrion-security-marketplace (api-security)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'cloudyrion/cloudyrion-security-marketplace (api-security)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
3 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 52 findings across every scanner that examined this package. None of the 1 finding rated critical by their scanner were dismissed.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
2 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Critical SQL injection risk and shell execution capabilities
The artifact contains a critical SQL injection vulnerability in `/repo/plugins/cloudyrion-security/skills/attack-scenarios/SKILL.md`. It also includes instructions that enable fetching raw content and piping it directly to a shell for execution, specifically in `/repo/plugins/cloudyrion-security/skills/sbom/SKILL.md`. Additionally, the artifact's marketplace configuration has a high-severity finding in `.claude-plugin/marketplace.json`.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
