This permits server-controlled code to run in the embedding page's origin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-14T00:07:12.612Z - **Finished:** 2026-08-14T00:08:09.169Z - **Download time:** 756 ms - **Static scan time:** 30 ms - **AI review time:** 55771 ms - **Total time:** 56557 ms ## Security analysis ### Published attack-surface review - **Summary:** When the bundled browser script is loaded into a document, it retrieves relative JavaScript modules and executes their text. This permits server-controlled code to run in the embedding page's origin. - **Trigger:** A consumer includes or otherwise executes a5yjlvj.js in a browser document. - **Impact:** Remote content served under the relative module path can execute with the privileges of the hosting web page. - **Evidence paths:** a5yjlvj.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-14T00:08:09.169Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** relative remote-module fetch followed by dynamic Function execution - **Rationale:** The package has no install-time execution, but its sole bundled asset is an obfuscated browser loader that dynamically fetches and executes server-provided code. That is a concrete, unresolved remote-code-execution capability for consumers who load the asset. - **Files touched:** a5yjlvj.js, package.json - **Network endpoints:** /b/\.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** a5yjlvj.js fetches JavaScript modules at runtime from a relative base path., Fetched response text is immediately executed with new Function., The browser bootstrap runs automatically when document exists, enabling the remote-module loader., The only source asset is heavily obfuscated and embeds large encoded code blobs. - **Evidence against:** package.json contains no lifecycle scripts, main, bin, or module entrypoint., No Node filesystem, environment, child-process, credential, or explicit external-host access was found., The remote module base is relative (/b/), so no fixed exfiltration endpoint is embedded. ## Public findings ### 1.
