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		[email protected] is a AI-detected potential code anomaly. Notes: The code is a security-conscious utility for running a compiler subprocess and collecting its output. It uses temporary files and careful stream handling to avoid large buffers and ensure proper cleanup. No suspicious data leakage, hardcoded credentials, or backdoors are evident. The primary risk is the inherent risk of spawning external processes, but this is standard for compilers in build tools and is mitigated by controlled I/O and error handling. Confidence: 0.75 Severity: 0.55 From: package-lock.json → npm/[email protected] 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 [email protected]. 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.

Block		[email protected] is a AI-detected potential code anomaly. Notes: This fragment appears to be a bundler-generated bootstrap/initialization piece that imports many modules and executes an initialization function (r). No explicit malicious activity is evident within this fragment itself, but the risk stems from side effects of the imported modules on load. A careful review of the implementations of the imported modules (especially those exporting r and those performing initialization, build-time, or network/file operations) is recommended to rule out hidden telemetry, backdoors, or undesired side effects.

Block		[email protected] is a AI-detected potential code anomaly. Notes: The analyzed code appears to implement a standard in-memory cache batch operation flow (put/delete) with careful handling of response bodies by buffering and storing bytes for caching. No signs of malware, data exfiltration, backdoors, or obfuscated behavior were found. The primary security considerations relate to memory usage from buffering potentially large response bodies and ensuring robust validation within batch operations to prevent cache state corruption. Overall risk is moderate, driven by in-memory data handling rather than external communication.

Block		[email protected] is a AI-detected potential code anomaly. Notes: The code implements a standard EventTarget-like mixin for wrapping event listeners and dispatching events to user callbacks. There are no suspicious patterns such as dynamic code execution, hardcoded secrets, or network activity. The risk is contingent on what the consumer does inside their handlers; the snippet itself does not introduce malware or data leakage mechanisms beyond normal event dispatch. Overall security risk is low in isolation.

Block		[email protected] is a AI-detected potential code anomaly. Notes: No explicit network exfiltration, reverse shell, or credential theft is present in this fragment. However, the code assembles and compiles arbitrary code via the Function constructor and invokes passed-in functions immediately (twice). That behavior constitutes a strong dangerous primitive (arbitrary code execution) which can be abused if any inputs (strings or args) are attacker-controlled. Treat this module as risky in threat models where inputs are not fully trusted; review call sites and sanitize/validate inputs or avoid dynamic evaluation.
