What is MAL-2026-10903?
MAL-2026-10903 is a malicious package in solana-web3-stable, published on 20 Jul 2026.
Official description
Package name 'solana-web3-stable' closely resembles the widely-used @solana/web3.js library, raising typosquat concern. The bundled lib/index.cjs.js and lib/index.esm.js contain co-located uses of child_process, hardcoded fetch/POST calls, and shell utilities (curl, ping). These keyword co-occurrences in a minified bundle are consistent with both a legitimate Solana client (which makes RPC POST/GET calls) and a malicious exfiltration shape; semantic verification of the actual call graph was not completed, so intent cannot be confirmed from the captured evidence alone. Routing to human review to confirm whether the network destinations are documented Solana RPC endpoints or attacker-controlled hosts, and whether child_process is invoked at install/import time.
What should I do about MAL-2026-10903?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
