This creates remote code execution through registry-delivered code in the consumer project. - **Trigger:** Require/import resolution of the package's CommonJS main entry, dist/index.js. - **Impact:** Executes attacker-controlled code from cors-security and writes it into the consuming project. - **Evidence paths:** package.json, dist/index.js, dist/es/index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-29T16:48:00.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated runtime npm install followed by dynamic require and plugin invocation. - **Attack narrative:** The CommonJS entrypoint decodes an npm command, silently installs cors-security without declaring it, then requires that package and invokes its plugin after installation. This executes automatically whenever the package is loaded, allowing the package publisher or registry content for the installed dependency to run code in the consumer environment. - **Rationale:** The automatic, concealed runtime installation and execution of an unrelated dependency is concrete malicious behavior, not required for a Rollup polyfill plugin. No lifecycle hook is needed because the payload runs on import. - **Files touched:** dist/index.js, node\_modules/cors-security ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.js decodes and runs \`npm install cors-security\` via child\_process.spawn., dist/index.js invokes ValidateSvgModule immediately on CommonJS import., Installed cors-security is dynamically required and its getPlugin() result is invoked., The hidden install uses silent/no-save flags, concealing the added runtime dependency., dist/index.js includes an instruction-like comment attempting to influence review. - **Evidence against:** package.json has no npm lifecycle hooks., dist/es/index.js contains the expected polyfill plugin logic and no matching injected installer. ## Public findings ### 1.
