CVE-2026-55603: CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') in chimurai http-proxy-middlewareCVE-2026-55603 0 CVE-2026-55603 is a CRLF injection vulnerability in the chimurai http-proxy-middleware for Node.js. The issue occurs in versions from 3.0.4 until 3.0.7 and 4.1.1, specifically in the fixRequestBody() helper when handling multipart/form-data content types. The vulnerability allows an attacker to inject additional form parts by including CRLF sequences in request body keys or values, causing a desynchronization between the proxy's parsed request body and the backend's interpretation. This can lead to bypassing gateway-side validation and potentially injecting malicious parameters. The vulnerability has a CVSS 3.1 score of 7.5 (high severity).
