CVE-2026-55677 Echo: Encoded slash (%2F) bypasses route-level protection and exposes static files

Echo is a Go web framework. Prior to 4.15.3 and 5.2.0, Echo's router and static file handler disagree on URL path decoding. The router matches routes using the raw encoded path preserving %2F as-is, while StaticDirectoryHandler unescapes %2F to / before resolving filesystem paths. This allows an...
