AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection confirms concrete malicious behavior: hidden detached execution of remotely fetched code unrelated to a React/DOM package or normal logger middleware. Lack of install hooks limits trigger scope but does not mitigate the runtime RCE loader. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-07-03T06:01:04.810Z - **Finished:** 2026-07-03T06:01:42.624Z - **Download time:** 509 ms - **Static scan time:** 72 ms - **AI review time:** 37232 ms - **Total time:** 37814 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:** The package contains a runtime remote code execution loader. Calling the exported middleware spawns a detached Node process that downloads JavaScript from jsonkeeper.com and executes it with access to require. - **Trigger:** User/application calls the default exported middleware from index.js. - **Impact:** Arbitrary remote JavaScript can run in the consumer environment with Node require access; final payload behavior is controlled off-package. - **Evidence paths:** package.json, index.js, lib/caller.js - **Review source:** ai\_review - **Reviewed:** 2026-07-03T06:01:42.624Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached child\_process plus remote dynamic code execution - **Attack narrative:** A consumer importing the package and invoking its middleware causes index.js to spawn a detached Node process running lib/caller.js. That script requests https://jsonkeeper.com/b/D3GLF with a secret-like header, reads data.cookie from the response, compiles it with Function.constructor, and invokes it with require. This gives the remote payload arbitrary Node module access outside the audited package source. - **Rationale:** Source inspection confirms concrete malicious behavior: hidden detached execution of remotely fetched code unrelated to a React/DOM package or normal logger middleware. Lack of install hooks limits trigger scope but does not mitigate the runtime RCE loader. - **Files touched:** lib/caller.js - **Network endpoints:** https://jsonkeeper.com/b/D3GLF, https://jsonspack.com/issues ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** lib/caller.js fetches remote data from https://jsonkeeper.com/b/D3GLF., lib/caller.js executes fetched data.cookie via new Function.constructor("require", s)., index.js runs lib/caller.js in a detached ignored child process when exported middleware is invoked., lib/caller.js retries the remote execution up to five times and suppresses errors., Package presents logger-like files/docs while package name is react-next-dom, indicating likely masquerading. - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle scripts., Remote execution is not triggered merely by npm install or by requiring index.js; it triggers on middleware invocation., No direct credential or filesystem harvesting is visible in packaged source before the remote payload executes. ## Affected versions and remediation This report applies to react-next-dom@17.2.8. - Avoid installing react-next-dom@17.2.8. 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.
