Hi,

The following vulnerability was published for golang-github-labstack-echo.

CVE-2026-55677[0]:
| 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 attacker to bypass route-level
| access controls and read static files without authorization. This
| vulnerability is fixed in 4.15.3 and 5.2.0.


If you fix the vulnerability please also make sure to include the
