CVE-2026-111755 · Severity: high · CVSS 4 · Published 2026-10-19

follow-redirects is a Node.js library that automatically follows HTTP redirects while protecting sensitive headers like authentication tokens. A flaw in the filtering logic allows headers with special characters (^ and |) in their names to bypass protection when redirects occur to attacker-controlled destinations, potentially exposing credentials to attackers.

Technologies: Follow-Redirects, follow-redirects (npm). Vendors: Follow-Redirects, npm.

Technical details

The escapeRegex function in follow-redirects versions 1.16.0 through 1.16.1 failed to escape regular expression metacharacters ^ and | used in sensitiveHeaders configuration, causing regex filters to fail matching sensitive header names containing these characters. When a cross-origin or HTTPS-to-HTTP redirect occurs, unescaped metacharacters prevent the generated filter from matching the intended header name, allowing credential headers to be forwarded to attacker-controlled redirect targets.
