Warning

MetaMask internal reviewing guidelines:

  • Do not ignore-all
  • Each alert has instructions on how to review if you don't know what it means. If lost, ask your Security Liaison or the supply-chain group
  • Copy-paste ignore lines for specific packages or a group of one kind with a note on what research you did to deem it safe.

Action Severity Alert  (click "▶" to expand/collapse)
Warn Low
Potential code anomaly (AI signal): npm rxjs is 100.0% likely to have a medium risk anomaly

Notes: The code is a standard, non-malicious implementation of a findIndex operator in an RxJS-like library. It does not perform external I/O, data exfiltration, or privileged actions.

Confidence: 1.00

Severity: 0.60

From: ?npm/@ledgerhq/devices@7.0.7npm/rxjs@6.6.7

ℹ Read more on: This package | This alert | What is an AI-detected potential code anomaly?

Next steps: Take a moment to review the security alert above. Review the linked package source code to understand the potential risk. Ensure the package is not malicious before proceeding. If you're unsure how to proceed, reach out to your security team or ask the Socket team for help at support@socket.dev.

Suggestion: An AI system found a low-risk anomaly in this package. It may still be fine to use, but you should check that it is safe before proceeding.

Mark the package as acceptable risk. To ignore this alert only in this pull request, reply with the comment @SocketSecurity ignore npm/rxjs@6.6.7. You can also ignore all packages with @SocketSecurity ignore-all. To ignore an alert for all future pull requests, use Socket's Dashboard to change the triage state of this alert.

Warn Low
Potential code anomaly (AI signal): npm rxjs is 100.0% likely to have a medium risk anomaly

Notes: The analyzed code is a standard, benign RxJS operator (pairwise) that emits pairs of consecutive values. There is no evidence of data exfiltration, backdoors, or malicious behavior. The source map reference is normal for development artifacts.

Warn Low
Potential code anomaly (AI signal): npm rxjs is 100.0% likely to have a medium risk anomaly

Notes: The analyzed code is a standard, non-malicious implementation of a VirtualTimeScheduler used by RxJS for testing or simulated time control. No malicious behavior detected; no data leakage, backdoors, or exfiltration mechanisms present. The security posture is favorable for its intended use as a unit-test/time-simulation utility.

Warn Low
Potential code anomaly (AI signal): npm rxjs is 100.0% likely to have a medium risk anomaly

Notes: The code is a conventional, well-scoped implementation of an RxJS-like concat operator. No malicious behavior, data exfiltration, or suspicious I/O detected in this fragment. Security risk is low; malware likelihood is negligible for this isolated operator function.

Confidence: 1.00

Warn Low
Potential code anomaly (AI signal): npm tar is 100.0% likely to have a medium risk anomaly

Notes: This module acts as a standard tar extraction wrapper using synchronous and asynchronous code paths. There is no evident malicious activity within this fragment. Security risk hinges on the behavior of the Unpack/UnpackSync implementation and how tar entries are written to disk (e.g., path traversal). No hardcoded secrets or network calls are present here. Recommend ensuring tar extraction handles path traversal and destination path sanitization in Unpack, and consider validating opt.file presence and type before streaming.
