No other attack behavior was identified in the inspected source. - **Trigger:** Importing or serving script.js through its main or unpkg entrypoint in a browser. - **Impact:** The operator receives a beacon that the script executed and may receive ordinary request metadata. - **Evidence paths:** package.json, script.js - **Review source:** ai\_review - **Reviewed:** 2026-09-21T23:55:08.245Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script assigns a webhook URL to a newly created Image object, triggering a browser fetch. - **Rationale:** The automatic third-party XSS beacon is a concrete suspicious behavior, but the source contains no lifecycle execution, secret collection, or destructive action that justifies blocking publication. - **Network endpoints:** https://webhook.site/4c14c8e4-721e-471d-807c-1a2aa216512a/?XSS\_works ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest makes script.js the package entrypoint., The entrypoint immediately creates an image whose source is a third-party webhook URL marked as an XSS beacon. - **Evidence against:** There are no lifecycle hooks, file operations, subprocess calls, or credential access in the inspected files. ## Affected versions and remediation This report applies to npmscript\_tesstalert\_unpkg@1.1.3. - Review the evidence and your use of npmscript\_tesstalert\_unpkg@1.1.3 before allowing it.
