Prior to 4.16.0 and 5.4.0, Echo's static file handlers can normalize dot segments after route matching and serve a file through a public static route even though the corresponding direct path is protected by route-level middleware. An unauthenticated attacker can read files that an application intended to protect with route-level middleware, when those files are also reachable through a static filesystem mount after path normalization. This vulnerability is the result of an incomplete fix for CVE-2026-55677. This issue is fixed in 4.16.0 and 5.4.0.","published":"2026-10-28T20:17:22.550","modified":"2026-10-28T20:17:22.550","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/labstack/echo/commit/b838391e2eade87ae7e5a09d7bb5087bec271ec1","label":"labstack/echo@b838391"},"references":[{"type":"WEB","url":"https://github.com/labstack/echo/commit/b838391e2eade87ae7e5a09d7bb5087bec271ec1"},{"type":"WEB","url":"https://github.com/labstack/echo/commit/fc410094b2f3415cf2bf5204082137b205bfd5af"},{"type":"WEB","url":"https://github.com/labstack/echo/releases/tag/v4.16.0"},{"type":"WEB","url":"https://github.com/labstack/echo/releases/tag/v5.4.0"},{"type":"WEB","url":"https://github.com/labstack/echo/security/advisories/GHSA-3pmx-cf9f-34xr"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T20:17:22.550"}}
