CVE-2026-118655

Echo is a Go web framework. Prior to 4.15.3 and 5.2.0, middleware.Static can decode an already decoded Request.URL.Path a second time. Double-encoded separators can consequently be reconstructed before filesystem resolution. This can reach a file under a guarded route when the static middleware i...

Path Equivalence

Overview Affected versions of this package are vulnerable to Path Equivalence in the pathWithoutMatrixParams of AbstractPathMatchingHttpSecurityPolicy via specially crafted HTTP requests containing encoded semicolons, slashes, or backslashes in the request path. An attacker can gain unauthorized...

CVE-2026-6321

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator URL containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization...

GHSA-X428-GHPX-8J92 @fastify/static vulnerable to route guard bypass via encoded path separators

Impact @fastify/static v9.1.0 and earlier decodes percent-encoded path separators %2F before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/ do not match /admin%2Fsecret.html, but @fastify/static decodes it to...
