CVE-2026-66064

MEDIUM

goshs has ACL Bypass & Path Traversal

Title source: cna
STIX 2.1

Description

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.
