 # Changelog
 
+## v5.2.0 - 2026-06-14
+
+**Security**
+
+* fix(static): reject encoded path separators that bypass route-level middleware by @vishr in https://github.com/labstack/echo/pull/3009
+* fix(middleware/static): don't double-unescape request path (#2599) by @vishr in https://github.com/labstack/echo/pull/3006
+
+Fixes [GHSA-vfp3-v2gw-7wfq](https://github.com/labstack/echo/security/advisories/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`/`StaticFS` and the `Static` middleware are affected. Thanks to @a-tt-om and @oran-gugu for reporting.
