{"id":"CVE-2026-118650","published":"2026-10-28T20:17:21.850","lastModified":"2026-10-28T20:17:21.850","description":"Echo is a Go web framework. Prior to 4.16.0 and 5.4.0, a globally mounted middleware.Static instance can interpret an encoded request path differently from Echo's router because the router matches the still-encoded path while the static handler uses the decoded URL.Path. The advisory demonstrates an encoded slash resolving to a file under the static root through the global static middleware, but the source is internally inconsistent about whether a route or group guard protects the corresponding literal path in that global-mount configuration. This issue is fixed in 4.16.0 and 5.4.0.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-177","CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://github.com/labstack/echo/commit/b838391e2eade87ae7e5a09d7bb5087bec271ec1","tags":[]},{"url":"https://github.com/labstack/echo/commit/fc410094b2f3415cf2bf5204082137b205bfd5af","tags":[]},{"url":"https://github.com/labstack/echo/releases/tag/v4.16.0","tags":[]},{"url":"https://github.com/labstack/echo/releases/tag/v5.4.0","tags":[]},{"url":"https://github.com/labstack/echo/security/advisories/GHSA-375p-5qhx-8wq4","tags":[]}],"exploitRefs":[{"url":"https://github.com/labstack/echo/commit/b838391e2eade87ae7e5a09d7bb5087bec271ec1","tags":[]},{"url":"https://github.com/labstack/echo/commit/fc410094b2f3415cf2bf5204082137b205bfd5af","tags":[]},{"url":"https://github.com/labstack/echo/releases/tag/v4.16.0","tags":[]},{"url":"https://github.com/labstack/echo/releases/tag/v5.4.0","tags":[]},{"url":"https://github.com/labstack/echo/security/advisories/GHSA-375p-5qhx-8wq4","tags":[]}],"hasPoc":true,"ai":null}
