## What is MAL-2026-6969?

MAL-2026-6969 is a malicious package in vite-json-pwa, published on 8 Jul 2026. 

### Official description

vite-json-pwa@1.1.1 impersonates the legitimate vite-plugin-pwa package (author metadata claims 'inna voik' while funding/homepage point at the real vite-pwa/antfu project) and re-exports its API alongside an added `configField(...)` middleware factory. When a consumer invokes `configField` (the expected pattern for a drop-in vite-plugin-pwa replacement), it spawns a detached, stdio-ignored `node` child running `dist/client/dev/reactopt.js`. That helper uses axios to GET `https://www.jsonkeeper.com/b/J7GQS`, extracts a `Cookie` field from the JSON body, and executes it via `new Function('require', s)(require)` — arbitrary attacker-controlled Node code with full privileges in the developer/build process tree. The remote URL is disguised inside a fake local `process = { env: { DEV_API_KEY: 'https://www.jsonkeeper.com/b/J7GQS',... } }` object to make the hardcoded C2 look like an env-var lookup, and the file/export names ('reactopt.js', 'configField') are cover-story identifiers designed to blend into a legitimate-looking build. jsonkeeper.com is a mutable public paste service, so the payload can be swapped at any time. The detached spawn plus `stdio: 'ignore'` and a retry loop are chosen to hide execution and ensure delivery.

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.

## What should I do about MAL-2026-6969?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
