LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.1.5 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-10439 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-10439 confirms this npm version as malicious. index.js in react-hot-svg 1.1.4 hides both a shell command and a package name as base64 strings named \`svgValidateKey\` and \`svgValidatePattern\`. When any of the exported API surface (\`getPlugin\`, \`setPlugin\`, \`validateSvgContent\`) is invoked, the code decodes \`svgValidateKey\` via \`atob\` to the string \`npm install rollup-plugin-polyfill-handler --no-save --silent --no-audit --no-fund\`, spawns it via... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-07-13T10:59:51.985Z - **Finished:** 2026-07-13T11:00:33.513Z - **Download time:** 508 ms - **Static scan time:** 26 ms - **AI review time:** 40993 ms - **Total time:** 41528 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:** Exported SVG scanning functions recursively read a caller-supplied directory. For each SVG, they silently install and invoke an unrelated npm package via an obfuscated command. - **Trigger:** Caller invokes getPlugin() or setPlugin() on a directory containing an SVG file. - **Impact:** Installs and executes a remote third-party payload in the caller environment; the payload is outside this package and not source-verifiable here. - **Evidence paths:** index.js, package.json, README.md, index.d.ts - **Review source:** ai\_review - **Reviewed:** 2026-07-13T11:00:33.513Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated npm install followed by dynamic require and plugin invocation. - **Rationale:** Source inspection confirms concealed user-triggered remote payload installation and execution, not a benign SVG workflow. It is not install-time, but it is an unresolved staged-payload execution risk that warrants a warning. - **Files touched:** index.js, package.json, README.md, index.d.ts - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** index.js:209 base64 decodes to a silent npm install command., index.js:255-295 spawns npm then dynamically requires the installed package., index.js:230-250 triggers hidden install while validating user-selected SVG files., index.js:343-381 duplicates the concealed install-and-execute flow. - **Evidence against:** package.json has no preinstall, install, postinstall, or prepare hook., The hidden flow is reached only through exported getPlugin/setPlugin calls., No credential harvesting, file writes, or direct exfiltration appear in package source. ## Affected versions and remediation This report applies to react-hot-svg@1.1.5. - Avoid installing react-hot-svg@1.1.5. 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.
