What is MAL-2026-13429?
MAL-2026-13429 is a malicious package in @avi892nash/aegis-grid-runner, published on 6 Aug 2026.
Official description
The package's default
bin action starts an HTTP server (grid.mjs) that listens on GRID_RUNNER_PORT (default 7719). Incoming requests carry a base64-JSON x-job-meta header containing a cmd string plus a gzipped code tarball; the runner decodes the header, extracts the tarball, and invokes child_process.spawn on meta.cmd in a shell on the host running the runner. The runner boots unpaired by default and accepts pairing via POST /api/master; token authentication (GRID_TOKEN) is optional per README, so a peer able to reach the port can pair and drive arbitrary shell command execution on the host. The bundle also contains references to internal Juspay infrastructure (ssh://[email protected]/picaf/aegis.git) and internal LAN addresses (192.168.0.50:7719, 192.168.0.146:7717) used as example onboarding strings, indicating an internal tool published to the public registry.What should I do about MAL-2026-13429?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
