# Security Audit Report — @flowy11/imagician - **Report ID:** `e505e5e0-17e5-46e7-a58a-c6851e8e9cc8` - **Generated:** 2026-07-21T23:26:46.017018+00:00 - **Signature:** unsigned (cosign keyless signing runs in CI; Req 22.4) ## 1. Executive Summary **Badge:** Verified (composite) **Security score:** 87.96 | Scanner | Badge | | --- | --- | | agent-audit-kit | Caution | | agentshield | Verified | | bearer | Verified | | cisco-skill-scanner | Caution | | nerlo-behavioral | Verified | | nerlo-install-instruction | Verified | | osv-scanner | Verified | | trivy | Verified | | Severity | Findings | | --- | --- | | critical | 0 | | high | 5 | | medium | 1 | | low | 2 | @flowy11/imagician may be integrated with compensating controls: review the 5 high-severity findings below, restrict granted permissions to the minimum the manifest declares, and subscribe to monitoring alerts for score changes. ## 2. Source Provenance - **Repository:** https://github.com/flowy11/imagician - **Commit scanned:** `unknown` - **License:** MIT - **Maintainer:** Hongyi Wang - **Version:** 0.1.1 ## 3. Per-Scanner Detail ### agentshield (v1.4.0) — Verified / 100.0 No findings. ### cisco-skill-scanner (v2.0.11) — Caution / 82.5 - **[high] Critically low analyzability score** — Only 67% of skill content could be analyzed. 3 of 10 files are opaque to the scanner. The safety assessment has low confidence. (/repo:None) - **[low] Vague skill description** — Skill description is too short (16 chars). Provide detailed explanation. (/repo/SKILL.md:None) - **[informational] Skill does not specify a license** — Skill manifest does not include a 'license' field. Specifying a license helps users understand usage terms. (/repo/SKILL.md:None) ### agent-audit-kit (v0.3.26) — Caution / 63.0 - **[low] MCP server repo missing SECURITY.md or security_contact** — A repository whose name or pyproject keywords declare it as an MCP server ships without a top-level SECURITY.md AND without a 'security_contact' entry in marketplace.json / pyproject.toml / package.json. Anthropic's April 2026 SECURITY.md guidance makes this the baseline expectation so researchers have a channel. (SECURITY.md:None) - **[medium] Repo depends on a third-party agent-platform SDK** — The project depends on an agent-platform SDK (context-ai, langsmith, helicone, langfuse, humanloop, MCP SDK). Informational finding so reviewers audit the vendor's OAuth-scope footprint before merging. Raised to MEDIUM because the April 19 2026 Vercel × Context.ai incident showed a single vendor compromise can turn into a production breach via transitive OAuth grants. (package.json:46) - **[high] MCP server built on the upstream SDK without STDIO sanitizer** — Repository declares a dependency on the upstream Anthropic / ModelContextProtocol SDK (Python 'mcp' / 'modelcontextprotocol', TS '@modelcontextprotocol/sdk', Java 'io.modelcontextprotocol:*', Rust 'mcp' / 'modelcontextprotocol') and exposes a STDIO transport ('StdioServerTransport', 'stdio_server', etc.) without a sanitizer on argv assembly. Anthropic declined to CVE this as working as designed — sanitization is the developer's responsibility. The OX Security disclosure on 2026-04-15 rolled up L (src/index.ts:None) - **[high] Vulnerable MCP SDK version pinned (DNS-rebinding fix missing)** — A project dependency manifest (requirements.txt, pyproject.toml, package.json, pom.xml, build.gradle) pins an MCP SDK at a version below the DNS-rebinding fix. Patched versions: Python 'mcp' >= 1.23.0, TS '@modelcontextprotocol/sdk' >= 1.21.1, Java 'io.modelcontextprotocol.sdk:mcp-core' >= 0.11.0, '@apollo/mcp-server' >= 1.7.0. Even if the project never serves over StreamableHTTP itself, transitive servers built on the SDK inherit the bug. (package.json:None) ### bearer (v2.0.2) — Verified / 100.0 No findings. ### nerlo-behavioral (v0.1.0) — Verified / 100.0 No findings. ### nerlo-install-instruction (v0.1.0) — Verified / 100.0 No findings. ### trivy (v0.71.0) — Verified / 85.0 - **[high] Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default** — MCP TypeScript SDK is the official TypeScript SDK for Model Context Protocol servers and clients. Prior to 1.24.0, The Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication with StreamableHTTPServerTransport or SSEServerTransport and has not enabled enableDnsRebindingProtection, a malicious website could exploit DNS rebinding to bypass same-origin policy rest (package-lock.json:None) ### osv-scanner (v2.3.8) — Verified / 85.0 - **[high] GHSA-w48q-cv73-mx4w — npm @modelcontextprotocol/sdk@0.5.0** — aliases: CVE-2025-66414, GHSA-w48q-cv73-mx4w \| CVSS: 7.6 (/repo/package-lock.json:None) ## 4. Threat Model Threat model synthesis has not yet run for this scan. This section is generated by the registry's LLM pipeline (Req 22.3) and will appear in the next regeneration of this report. ## 5.
