CVE-2026-109332

LowCVSS 3.1
Published: Updated: Translated: NVD NIST

Summary

Network-AI (npm network-ai) before 5.15.2 contains an origin validation error in McpSseServer._handleRequest in lib/mcp-transport-sse.ts that reflects localhost Origins into Access-Control-Allow-Origin regardless of bind interface. When the server binds a non-loopback address, an attacker page with a localhost Origin visited by a victim can read unauthenticated endpoints like /health cross-origin.

Risk Assessment

The vulnerability allows an attacker to read sensitive data from unauthenticated endpoints, potentially leading to information disclosure.

Recommendation

It is recommended to update network-ai to version 5.15.2 or later, which includes the fix.
