mdb-vitenpm
Advisory published Updated
mdb-vite is a confirmed malicious npm package (MAL-2026-10144) that steals credentials and exfiltrates sensitive data (malicious version 1.5.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in mdb-vite (npm)
What this malware does
The package's default export getPlugin performs an HTTPS fetch to https://svganchordev.net/icons/107 with URL components split across protocol, domain, separator, and path variables to disguise the destination, then passes the response's credits field to new Function('require','module',...,data.credits) and invokes it with full Node capabilities (require, module, process, Buffer, global, __dirname=process.cwd()). Any consumer that imports the package and invokes the default export runs attacker-controlled code with the installer's Node privileges — enabling arbitrary payload delivery, credential theft, persistence, or downstream compromise. Additional misdirection: the package name mdb-vite evokes MDBootstrap/Vite tooling, keywords are react, helper, svg, the README titles itself polymarket-clob-api, and package.json describes it as a Polymarket CLOB SDK — none of which match the code, which only fetches and evals remote JavaScript. A bearrtoken: 'logo' header and an unused CDN-provider map (cloudflare/fastly/akamai/cloudfront) are decoys to make the loader appear CDN-related.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for mdb-vite (version 1.5.2).
If you installed it — respond
mdb-vite is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If mdb-vite 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 mdb-vite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
