goshs 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.

HIGHPre-NVD 7.57.5—Elevated
EchelonGraph scoreMEDIUM confidence
This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 79% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
