CVE-2026-111755
HIGHDescription
follow-redirects is a Node.js HTTP and HTTPS client wrapper that automatically follows redirects. From 1.16.0 until 1.16.1, escapeRegex leaves valid header-name metacharacters unescaped in sensitiveHeaders. When an application declares a sensitive header whose name contains ^ or | and follows a cross-origin or HTTPS-to-HTTP redirect, unescaped regular-expression metacharacters prevent the generated filter from matching the declared header name, and the credential header is forwarded to an attacker-controlled redirect target. This issue is fixed in version 1.16.1.
