Caution

Review the following alerts detected in dependencies.

According to your organization's Security Policy, you must resolve all "Block" alerts before proceeding. Learn more about Socket for GitHub.

Action	Severity	Alert  (click "▶" to expand/collapse)
Block		Potential code anomaly (AI signal): npm @rolldown/binding-wasm32-wasi is 100.0% likely to have a medium risk anomaly Notes: The JS loader is not itself executing obvious malicious JavaScript (no eval, no external network calls, no hard-coded credentials). However it intentionally grants a WebAssembly module broad privileges: it passes the full process.env into WASI and the worker, and preopens the host filesystem root so the wasm can access the filesystem. It also forwards worker messages into a filesystem proxy function. These design choices make running an untrusted or tampered-with wasm binary dangerous: a malicious wasm could read environment variables, enumerate and modify host files, and exfiltrate data via any network capability inside the wasm or worker. Therefore the module should be treated as high-risk if the wasm artifact (local file or npm package) is not from a trusted source. Recommended mitigations: avoid preopening the root (limit to specific directories), avoid passing full process.env, validate integrity of the wasm binary (signing/checksums), and avoid installing untrusted package replacements. Confidence: 1.00 Severity: 0.60 From: ? → npm/tsdown@0.21.5 → npm/@rolldown/binding-wasm32-wasi@1.0.0-rc.11 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/@rolldown/binding-wasm32-wasi@1.0.0-rc.11. 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.
