Security readout for executives and security teams
Plain-English summary
CVE-2022-31150 affects undici, a Node.js HTTP/1.1 client. If an application lets untrusted input influence outbound request headers, an attacker may inject line breaks into those headers. The documented impact is limited integrity risk, not data theft or service outage, but exposed services should still update or sanitize inputs.
Executive priority
Prioritize normal patch-cycle remediation unless the application processes untrusted input into outbound headers. Raise urgency for internet-facing services, multi-tenant systems, or vendor appliances where affected undici versions are confirmed.
Technical view
The issue is CWE-93 CRLF injection in undici request headers. The source bundle reports vulnerable undici versions below 5.7.1 and a fix released in 5.8.0. CVSS 3.1 is 5.3, network exploitable, low complexity, no privileges or user interaction, unchanged scope, integrity low.
Likely exposure
Exposure is most likely in Node.js applications or products that directly or transitively use undici and create outbound HTTP headers from user-controlled or external data. The bundle also includes a NetApp advisory, suggesting downstream product impact may exist and should be checked with vendors.
Exploitation context
The provided data does not show active exploitation, and KEV is false. Exploitation would require a reachable application path where attacker-influenced data is copied into undici request headers without CRLF sanitization. Do not assume exploitability from package presence alone.
Researcher notes
Evidence is sufficient for affected component, weakness class, CVSS, workaround, and fixed release. The version boundary in the bundle mentions both below 5.7.1 and fix release 5.8.0; verify exact package exposure against the GitHub advisory and installed dependency metadata.
Mitigation direction
- Upgrade undici to the vendor fixed release, version 5.8.0 or later.
- Sanitize all untrusted HTTP header values to remove CRLF sequences.
- Review downstream vendor advisories for embedded undici usage.
- Rebuild and redeploy affected containers or packages after dependency updates.
Validation and detection
- Check lockfiles and SBOMs for undici versions in production builds.
- Confirm scanners no longer report CVE-2022-31150 after remediation.
- Review code paths that set outbound HTTP headers from external input.
- Add tests that reject CRLF in untrusted header values.

Improper Neutralization of CRLF Sequences ('CRLF Injection')
Improper Neutralization of CRLF Sequences ('CRLF Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
