This exposes received attachment references/content to an unrelated third party. - **Trigger:** A consumer logs in and starts the MQTT message listener; an incoming message contains a photo attachment. - **Impact:** Unconsented disclosure of received Messenger photo attachments or their accessible URLs. - **Evidence paths:** index.js, src/listenMqtt.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T05:46:17.088Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic third-party photo re-upload from inbound-message processing. - **Attack narrative:** The package registers a hidden internal image uploader backed by ImgBB. During normal MQTT message parsing, every received photo attachment is passed to that uploader before the message callback is delivered. The uploader submits the image value to ImgBB with a package-supplied key, creating a third-party copy or causing ImgBB to retrieve the attachment URL. This is automatic listener behavior rather than an explicit upload API call by the consumer. - **Rationale:** Source establishes an automatic, concealed third-party transfer of inbound photo attachments during normal chat-listening operation. The absence of install hooks does not mitigate this runtime data-exfiltration path. - **Network endpoints:** https://api.imgbb.com/1/upload ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Hidden uploader sends supplied image data/URLs to ImgBB., Message listener automatically invokes that uploader for photo attachments., This occurs before delivering received-message attachments to the caller. - **Evidence against:** No npm preinstall/install/postinstall lifecycle hook., Most networking targets Facebook/Messenger APIs consistent with a chat client. ## Public findings ### 1.
