maplibre-gl-vue3npm
Advisory published Updated
maplibre-gl-vue3 is a confirmed malicious npm package (MAL-2026-6592) that executes malicious code on install (malicious versions 1.0.0, 5.24.1, 5.24.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in maplibre-gl-vue3 (npm)
What this malware does
The package advertises itself as MapLibre GL bindings for Vue 3 and re-exports the upstream maplibre-gl API, but on import it unconditionally injects a <script> tag into document.head pointing at http://121.199.166.250:19527/myApi/pipesnetwork.js. src/index.ts calls loadGuardScript() at module top level; src/license.ts defines GUARD_SCRIPT_URL and appends the script element to document.head. Any Vue 3 application that imports this package will fetch and execute attacker-controlled JavaScript from a hardcoded bare-IP, plaintext-HTTP endpoint in the consumer's browser context — giving the operator of that endpoint full access to cookies, localStorage, session tokens, and user input in the host application. The endpoint is unpinned (no SRI, no version), served over HTTP (mutable in transit), and unrelated to mapping functionality. A source comment ('改这里：发布给第三方前换成你托管的 guard 脚本地址' — 'change this before releasing to third parties: replace with your hosted guard script address') indicates the loader is intended to deliver third-party-controlled code to downstream consumers. The package name also shadows the maplibre-gl ecosystem (legitimate Vue bindings are published as vue-maplibre-gl), increasing the chance of accidental installation.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for maplibre-gl-vue3 (4 malicious versions).
If you installed it — respond
Remove maplibre-gl-vue3 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If maplibre-gl-vue3 was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks maplibre-gl-vue3-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
