CVE-2026-53624 | Fiber is an Express inspired web framework written in Go. Pr… | CVSS 4.8 MEDIUM

Description

Fiber is an Express inspired web framework written in Go. Prior to 3.4.0, the helmet middleware in middleware/helmet/helmet.go never sets the Strict-Transport-Security response header even when HSTSMaxAge is configured because it checks c.Protocol() for https instead of c.Scheme(). This issue is fixed in version 3.4.0.
