MAL-2026-12018 Malicious code in @keyv/mysql (npm)

@keyv/mysql is the MySQL storage adapter for the keyv key-value abstraction. No exfiltration, install-time fetch-and-execute, silent-relay, credential distribution, backdoor, or install-time destructive behavior was identified in the package contents. No lifecycle hooks perform outbound network activity to attacker-controlled destinations, and no installer-secret paths are read.

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.
