Group middleware logic changes
PR #2996 reverts back to v4 behavior for a group registering implicit 404 handlers.
If you do not want this behavior, you do not want implicit 404 handlers for groups, use:
e := echo.NewWithConfig(echo.Config{NoGroupAutoRegister404Routes: true})
g := e.Group("/api")
Other noteworthy echancements:
* Adds first-class support for the QUERY HTTP method RFC 10008 in #3038
e.QUERY("/", func(c *Context) error {
return c.String(http.StatusTeapot, "OK")
})
* Router: automatically handle HEAD request by GET handlers in https://github.com/labtack/echo/pull/2949
e := echo.NewWithConfig(echo.Config{
Router: echo.NewRouter(echo.RouterConfig{
AutoHandleHEAD: true,
}),
})
What's Changed
* perf(json): pooled-buffer JSON deserialize by @vishr in #3023
* perf(router): cache-friendly static child lookup by @vishr in #3024
* update golang.org/x deps to latest versions by @aldas in #3034
* pin GitHub Actions to full commit SHAs and rework actions SHAs to own variables by @aldas in #3035

Make serving static file releated methods and middleware not unescape path by default - so how the way Router interprets paths and Static methods/middleware is consistent.
Given following situation:
// 0.
// given folder structure:
// private.txt
// public/
// public/index.html
// public/text.txt
// public/admin/private.txt
// 1. share `public/` folder contents from the server root. This folder actually contains subfolder `admin` which
// contents we want to forbid from downloading
e.Static("/", "public")
// 2. naively assume that everything under /admin folder is now forbidden
e.GET("/admin/*", func(c *Context) error {
return ErrForbidden
})
Then requests to /admin%2fprivate.txt would not be matched to GET /admin/* route (routing does not look unescaped path) and static file serving will use unescaped path to serve the file.
Note: this way of "guarding" subfolders will never work for for paths like /assets/../admin%2fprivate.txt which will path.Clean("/assets/../admin%2fprivate.txt") to /admin/private.txt and are servable if static file serving is configured to unescape paths.
If you want to guard routes - use middlewares on Static* methods and before Static middleware.
* revert PR #3009 changes to just disabling path escaping by default in static methods/middleware by @aldas in #3016
Closes GHSA-vfp3-v2gw-7wfq more completely: the previous fix (#3009) rejected explicitly encoded
separators at the handler level; this patch makes the no-unescape behavior the default so new configurations are safe without extra opt-out steps.
What changed: DisablePathUnescaping (on StaticConfig and StaticDirectoryHandlerConfig) is deprecated and replaced by EnablePathUnescaping (default false). Path unescaping is now opt-in.
What this protects: With EnablePathUnescaping: false (new default), encoded separators (%2F, %5C) are never decoded before routing or file lookup, so they cannot
bypass route-level authentication or other middleware guards.
What this does NOT protect: Serving a directory with Static, StaticFS, or StaticDirectoryHandler exposes its entire subtree. Sibling routes are not a reliable
ACL boundary — attach authorization middleware directly to the static mount, or serve sensitive sub-trees under separate guarded routes.
Breaking change / migration: If you serve files whose names contain URL-encoded characters (e.g., /hello%20world.txt → hello world.txt), you must now opt in:
// Static middleware
e.Use(middleware.StaticWithConfig(middleware.StaticConfig{
EnablePathUnescaping: true, // only safe when NOT relying on route-based ACL guards
...
}))
// StaticDirectoryHandler
middleware.StaticDirectoryHandler(fs, &middleware.StaticDirectoryHandlerConfig{
EnablePathUnescaping: true,
})

Fixes GHSA-vfp3-v2gw-7wfq: an encoded path separator (%2F or %5C) in a static file URL could bypass route-level middleware (e.g. authentication on a sibling route) and disclose static files. Both StaticDirectoryHandler (used by Static/StaticFS) and the Static middleware are affected. Backport of the v5 fix (#3016, released in v5.2.1). Thanks to @a-tt-om and @oran-gugu for reporting.

Security
This change does not break the API contract, but it does introduce breaking changes in logic/behavior.
If your application is using c.RealIP() beware and read https://echo.labstack.com/docs/ip-address
In v5 the c.RealIP() will now return request.RemoteAddr unless e.IPExtractor has been configured. No potentially spoofable headers are used by default anymore.
Configure IPExtractor with proper trust options when you want to read IP from headers. See:
* https://pkg.go.dev/github.com/labstack/echo/v5#ExtractIPFromRealIPHeader
* https://pkg.go.dev/github.com/labstack/echo/v5#ExtractIPFromXFFHeader
v4 behavior can be restored with:
e := echo.New()
e.IPExtractor = echo.LegacyIPExtractor()
Related PR: Remove legacy IP extraction logic from context.RealIP method by @aldas in #2933
What's Changed
* Add echo-opentelemetry to the README.md by @aldas in #2908
* fix: correct spelling mistakes in comments and field name by @crawfordxx in #2916
* Add https://github.com/labstack/echo-prometheus to the middleware list in README.md by @aldas in #2919
* Add StartConfig.Listener so server with custom Listener is easier to create by @aldas in #2920
* Fix rate limiter documentation for default burst value by @karesansui-u in #2925
* Add doc comments to clarify usage of File related methods and leading slash handling by @aldas in #2928
* Add NewDefaultFS function to help create filesystem that allows absolute paths by @aldas in #2931
* Do not set http.Server.WriteTimeout in StartConfig by @aldas in #2932
