Security readout for executives and security teams

Plain-English summary

CVE-2021-35065 is an availability risk in the Node.js glob-parent package before 6.0.1. A specially crafted input can make a regular expression consume excessive CPU, potentially slowing or denying service to software that processes untrusted glob patterns.

Executive priority

Treat as a high-priority dependency hygiene and availability fix for internet-facing or multi-tenant Node.js services. It is less urgent than confirmed exploited remote code execution, but unpatched exposure can still cause outages if reachable.

Technical view

The issue is a regular expression denial of service weakness in glob-parent's enclosure regular expression, classified as CWE-1333. The CVSS 3.1 score is 7.5 because it is network-reachable, low-complexity, unauthenticated, and affects availability only.

Likely exposure

Exposure is most likely in Node.js applications, build systems, or vendor products that include glob-parent before 6.0.1 directly or transitively. The CVE source bundle does not provide precise CPEs, so confirm through lockfiles, SBOMs, and vendor advisories.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. Practical risk depends on whether attacker-controlled glob-like input reaches the vulnerable parsing path. Impact is service degradation or outage, not data theft or code execution based on the supplied evidence.

Researcher notes

The source bundle names glob-parent before 6.0.1 and links the upstream fix PR and commit, but affected CPE details are absent. Analysis should focus on transitive dependency resolution, reachable input paths, and vendor-packaged software that may carry the library.

Mitigation direction

  • Upgrade glob-parent to version 6.0.1 or later where present.
  • Refresh lockfiles and rebuild deployed artifacts after dependency updates.
  • Check Snyk, project, and vendor guidance for product-specific remediation.
  • If upgrade is blocked, reduce exposure to untrusted glob-pattern input.
  • Track vendor advisories for embedded or bundled dependency use.

Validation and detection

  • Search SBOMs and lockfiles for glob-parent versions before 6.0.1.
  • Confirm whether vulnerable versions are present in runtime artifacts, not only source trees.
  • Review application paths that accept externally supplied glob patterns.
  • Check vendor advisories for bundled products, including NetApp-listed exposure.
  • Verify dependency scanners no longer flag CVE-2021-35065 after remediation.
