CVE-2026-55677 Echo: Encoded slash (%2F) bypasses route-level protection and exposes static files

Echo is a Go web framework. Prior to 4.15.3 and 5.2.0, Echo's router and static file handler disagree on URL path decoding. The router matches routes using the raw encoded path preserving %2F as-is, while StaticDirectoryHandler unescapes %2F to / before resolving filesystem paths. This allows an...

CVE-2026-55677

Echo (Go framework) prior to 4.15.3 and 5.2.0 has a router vs static file handler decoding mismatch: the router uses the raw encoded path while StaticDirectoryHandler unescapes %2F to /, enabling bypass of route-level access controls to read static files without authorization. The vulnerability i...

CVE-2026-54286 concerns Hono’s path traversal in the Windows environment via encoded backslash (%5C) in the request path. A prior issue (pre-4.12.25) causes %5C to decode to a backslash, which Windows path resolution treats as a separator, allowing a crafted URL segment (e.g., admin\secret.txt) t...

Server-side Request Forgery (SSRF)

Overview starlette is a The little ASGI library that shines. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the StaticFiles file on Windows systems when handling UNC paths. An attacker can obtain NTLMv2 credentials of the service account by sending a...

Starlette: SSRF and NTLM credential theft via UNC paths in StaticFiles on Windows

Summary When serving static files on Windows, StaticFiles resolves the requested path with os.path.realpath. If a UNC path such as \attacker.com\share reaches the resolver, realpath causes the process to open a connection to the remote host over SMB port 445. This is a server-side request forgery...
