Release notes

Sourced from github.com/labstack/echo/v4's releases.

v4.15.3 - Static encoded-separator route bypass fix (GHSA-vfp3-v2gw-7wfq)

Security

• fix(static): reject encoded path separators that bypass route-level middleware by @​vishr in labstack/echo#3011

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 (#3009, released in v5.2.0). Thanks to @​a-tt-om and @​oran-gugu for reporting.
