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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-177","CWE-863"],"references":["https://github.com/labstack/echo/commit/b838391e2eade87ae7e5a09d7bb5087bec271ec1","https://github.com/labstack/echo/commit/fc410094b2f3415cf2bf5204082137b205bfd5af","https://github.com/labstack/echo/releases/tag/v4.16.0","https://github.com/labstack/echo/releases/tag/v5.4.0","https://github.com/labstack/echo/security/advisories/GHSA-375p-5qhx-8wq4"],"products":[],"source":"nvd","synced_at":"2026-10-28T20:41:45.883959281+00:00"},"epss":null,"kev":null,"osv":[{"id":"GHSA-375p-5qhx-8wq4","url":"https://osv.dev/vulnerability/GHSA-375p-5qhx-8wq4","summary":"Echo's middleware.Static: `%2F`-encoded path bypasses route/group middleware guarding a statically-served path","modified":"2026-10-28T20:15:05.439970416Z","packages":[{"ecosystem":"Go","name":"github.com/labstack/echo/v5","purl":"pkg:golang/github.com/labstack/echo/v5","ranges":["<5.4.0"],"fixed":["5.4.0"]},{"ecosystem":"Go","name":"github.com/labstack/echo/v4","purl":"pkg:golang/github.com/labstack/echo/v4","ranges":["<4.16.0"],"fixed":["4.16.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
