The 'priority-mutex-lane' npm package version 2.5.1 has been identified as containing malicious code or relying on a dependency that does. This malicious code can fully compromise any computer on which the package is installed or executed. The compromise may allow attackers to gain full control over the system, putting all stored secrets and keys at risk. The advisory strongly recommends immediate rotation of all credentials from a separate, uncompromised device. Removal of the package alone is insufficient to guarantee eradication of the malicious software or attacker access.

Full system compromise on any computer with the affected package installed or running. Potential exposure and theft of all secrets and keys stored on the compromised system. Persistent attacker control may remain even after package removal.

Remove the 'priority-mutex-lane' package version 2.5.1 immediately. Rotate all secrets and keys from a different, secure computer to prevent unauthorized access. Because the system may be fully compromised, consider a full system rebuild or forensic analysis to ensure complete removal of malicious software. There is no official patch or fix available; the package should be avoided entirely.
