Descriptiongoshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.1, the httpserver/updown.go bulkDownload handler for ?bulk&file= ZIP downloads did not call findEffectiveACL or applyCustomAuth, allowing unauthenticated reads of files protected only by .goshs folder ACLs and block lists. This issue is fixed in version 2.1.1. This vulnerability exists due to an incomplete fix for CVE-2026-40189.
