@sql-access/nodesql versions 1.0.5 through 1.1.8 (specific versions enumerated) are malicious decoy packages that do not perform their advertised SQL or Buffer polyfill functions. Instead, they inject a dynamic import statement that loads and executes the top-level code of an attacker-controlled package (@sqlite-node/createsql) at runtime. This results in silent execution of malicious code on any system that installs or requires @sql-access/nodesql. The package's README and code are inconsistent with its name and advertised purpose, indicating a supply-chain attack pattern involving namesquatting and dynamic code loading. The attack compromises the host system, potentially exposing all stored secrets and keys.

Systems with any of the affected @sql-access/nodesql package versions installed or running are considered fully compromised. The malicious package executes attacker-controlled code silently, potentially allowing unauthorized access, data exfiltration, or further system compromise. All secrets and keys stored on the compromised system should be considered exposed and must be rotated from a secure environment. Simply removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the attacker.

No official patch or fix is currently available for this malicious package. Immediate removal of @sql-access/nodesql from affected systems is recommended. All secrets, credentials, and keys stored on compromised systems should be rotated immediately from a different, trusted environment. Due to the high likelihood of full system compromise, consider rebuilding affected systems from known-good backups or reinstalling the operating system to ensure complete remediation.
