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. The preinstall hook is a benign Node version check, but the media helper exposes a shell command construction risk through interpolated paths. The available caller excerpt does not show that an attacker can control those paths, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-09T03:21:38.264Z - **Finished:** 2026-10-09T03:22:10.106Z - **Download time:** 780 ms - **Static scan time:** 1912 ms - **AI review time:** 29149 ms - **Total time:** 31842 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 video thumbnail helper interpolates filesystem paths into a shell command. This creates a potential command injection surface when a caller supplies a crafted path, but the inspected caller uses a generated output name and does not establish an attacker-controlled path. - **Trigger:** A caller requests video thumbnail generation and provides a file path that reaches the helper. - **Impact:** A crafted path could cause shell command execution under the package user's privileges; the inspected call path does not confirm attacker control of that input. - **Evidence paths:** lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T03:22:10.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper inserts path and output arguments into a command string passed to exec without shell escaping. - **Rationale:** The preinstall hook is a benign Node version check, but the media helper exposes a shell command construction risk through interpolated paths. The available caller excerpt does not show that an attacker can control those paths, so this warrants a warning rather than a block. - **Files touched:** lib/Utils/messages-media.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The video thumbnail helper builds a shell command by interpolating its path and output arguments, then calls exec., The thumbnail caller supplies a file path to that helper; the shown call uses a generated output path and fixed timestamp and dimensions., The preinstall hook only checks the Node.js major version and exits when it is below 20. - **Evidence against:** The preinstall script does not install payloads, modify project files, or contact a network endpoint., The inspected media upload path uses WhatsApp media connection hosts and a WhatsApp authentication token. ## Affected versions and remediation This report applies to @badzz88/baileys@8.4.0. - Review the evidence and your use of @badzz88/baileys@8.4.0 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.
