NVD Description

Note: Versions mentioned in the description apply only to the upstream lerna package and not the lerna package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
