Quarkus HTTP path-based authorization policies can be bypassed using encoded semicolons (%3B) to smuggle matrix parameters past the security layer, and using encoded slashes (%2F) or backslashes (%5C) to access protected static resources. This is a distinct issue from CVE-2026-39852, which addressed only literal semicolon stripping. ### Technical Details The security layer (AbstractPathM

goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.5, the httpserver/handler.go sendFile handler opened files using a cleaned path but derived the authorization filename from raw req.URL.Path, so a trailing slash could bypass .goshs ACL-file protection and block-list checks. This issue is fixed in version 2.1.5.

## Summary `sendFile` derives the served filename from the raw request path while opening the file from the cleaned path, so appending a trailing slash empties the derived name and defeats both the never-serve rule for the ACL file and the block list. ## Finding (Medium): trailing-slash ACL and hidden-file bypass httpserver/handler.go, sendFile (lines 789-801) takes the filename from the RAW r

`SanitizeFilePath` in `pkg/utils/utils.go` validated that a path stayed under a safe directory by calling `strings.HasPrefix(path, safedir)`. This is a lexical check, not a directory boundary check: `/packages-extra/evil` starts with `/packages`, so it passed. The function did not enforce a path-separator boundary, so any sibling directory whose name began with the safe-directory string was accept
