Malicious code in sjs-builder (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: ghsa-malware (6a36f6daf0c48b61b402287f9daea175fb059e04d48ee5e3e25b99f101962f34) 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.
AI Analysis
Technical Summary
The sjs-builder package versions 1.0.4 and 1.0.5 distributed via npm contain embedded malicious code. Installation or execution of these versions results in a full compromise of the host system, potentially allowing attackers complete control. Because the compromise may extend beyond the package itself, simply uninstalling the package is insufficient to restore system integrity. This threat is identified as MAL-2026-6876 and is tracked under GHSA-27jm-f99f-wqr4. No CVSS score or known exploits in the wild are reported.
Potential Impact
Any system with sjs-builder versions 1.0.4 or 1.0.5 installed or running is considered fully compromised. Attackers may have gained full control over the system, including access to stored secrets and keys. This level of compromise poses a severe risk to confidentiality, integrity, and availability of the affected system and any connected infrastructure.
Mitigation Recommendations
Remove the affected sjs-builder package versions 1.0.4 and 1.0.5 immediately. Rotate all secrets, keys, and credentials from a different, trusted system to prevent further unauthorized access. Because the system may be fully compromised, consider rebuilding or restoring the system from a known clean backup. No official patch or fix is available; remediation relies on removal and credential rotation.
