Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. No covert package-owned attack was identified, but two concrete unsafe capabilities remain. A caller-controlled media path reaches a shell command, and a caller-configured upload host can receive uploaded media plus a WhatsApp media authentication value. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-21T10:37:01.357Z - **Finished:** 2026-09-21T10:39:35.656Z - **Download time:** 251 ms - **Static scan time:** 1476 ms - **AI review time:** 152571 ms - **Total time:** 154299 ms The recorded confidence comes from the underlying analysis.

A caller-controlled media path reaches a shell command, and a caller-configured upload host can receive uploaded media plus a WhatsApp media authentication value. - **Trigger:** Calling video thumbnail generation with an attacker-controlled file path, or enabling a custom upload host and uploading media. - **Impact:** Command injection can execute code in the consuming process. A configured untrusted upload host can receive the media and a credential intended for WhatsApp media upload. - **Evidence paths:** lib/Utils/messages-media.js, lib/Defaults/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-21T10:39:35.656Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The thumbnail helper constructs an unescaped ffmpeg command for exec. The upload helper iterates custom hosts first, embeds uploadInfo.auth in the URL, and POSTs the media file. - **Rationale:** This is not evidence of malware or an install-time attack, but the active library code contains a command-injection vulnerability and conditional credential forwarding to an unrestricted caller-configured destination. These are material risks requiring a warning. ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The video-thumbnail helper interpolates a caller-provided path into a shell command and executes it with child\_process.exec, creating command-injection risk., Media upload prep puts caller-configured upload hosts ahead of WhatsApp-provided hosts and appends the current media authentication value to the URL., The upload transport POSTs the selected file path to that constructed URL., Custom upload hosts are empty by default, so credential exposure requires caller configuration., The install hook only runs a local Node-version check; no install-time payload or persistence was found. - **Evidence against:** No package-owned exfiltration endpoint, secret harvesting, self-dependency, or destructive behavior was found., The configured-host feature is inactive in the default connection configuration. ## Affected versions and remediation This report applies to my-auto-follow@1.0.4. - Review the evidence and your use of my-auto-follow@1.0.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
