On 2026-10-01 the remote list contained `120363418964199743@newsletter`, `120363410316899314@newsletter`, `120363429190136593@newsletter` and `120363429068662026@newsletter` (under the key `saurus`). The README lists \"Auto-follow\" only as a feature in a comparison table; it does not say that the library follows the publisher's channels by default.\n\nLine numbers refer to version 7.1.3; the same code is present in every published version listed under `affected`.\n\nStatic review of the published tarball(s) found no code that sends WhatsApp credentials or session keys off-host, no install-time payload (the only install hook is Baileys' stock Node.js version check in `engine-requirements.js`), and no persistence; the payload runs when an application creates a WhatsApp socket with the library. The harm is the covert use of the victim's account to inflate the publisher's channel subscribers.\n\nSHA-256 of the published npm tarball(s): 7.1.1: `37550f81f18467c3378bd7c402813841f2696372fba50a03a22fff0e21115984`; 7.1.2: `139dddeb58e8a04b9c6f4def85f759768b27de217cde6b577b262b5fe297fed3`; 7.1.3: `6adfeb716809fa59638b6476fca8cc6ef8c8a0fdb7fc9a54390d403879bb111e`.\n\n---\n_-= Per source details.

Its default export makeWASocket unconditionally invokes triggerAutoFollow, which — 90 seconds after a successful WhatsApp connection — issues FOLLOW iq stanzas from the installer's connected WhatsApp account. The targets are a hardcoded newsletter JID (120363400911374213@newsletter) plus a mutable list of JIDs fetched at runtime from https://raw.githubusercontent.com/iyedahruss/all-public-db/refs/heads/main/newsletter.json. The behavior is enabled by default (DEFAULT_CONNECTION_CONFIG.autoFollowNewsletterOnConnect: true) and is not documented; an opt-out exists via autoFollowNewsletterOnConnect:false. Because the followed-JID list is fetched at runtime from an author-controlled GitHub raw URL, the set of channels the installer's account subscribes to can be changed by the author after install. No installer credentials, filesystem data, or environment variables are read; no remote code is fetched or executed; no persistence or backdoor is installed. The static match on lib/Utils/generics.js referencing ping/GET is a standard HTTP GET performing the newsletter.json fetch, not exfiltration. The ping static hit relates to a generic keepalive/utility, not command execution against the installer.\n","state":0,"publishedAt":"2026-10-11T16:54:06+00:00","modifiedAt":"2026-10-11T17:30:48.0264672+00:00","affected":[{"ecosystem":"npm","name":"luoxy-baileys","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["7.1.1","7.1.2","7.1.3"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/","https://www.npmjs.com/package/luoxy-baileys","https://www.npmjs.com/package/luoxy-baileys/v/7.1.2","https://www.npmjs.com/package/luoxy-baileys/v/7.1.3","https://www.npmjs.com/package/luoxy-baileys/v/7.1.1"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17446","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17446","identifiers":["MAL-2026-17446"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
