CVE-2026-54719: CWE-862: Missing Authorization in goshs-labs goshs
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.
AI Analysis
Technical Summary
The vulnerability in goshs affects the httpserver/updown.go bulkDownload handler for ?bulk&file= ZIP downloads. Before version 2.1.1, this handler failed to invoke findEffectiveACL or applyCustomAuth functions, resulting in missing authorization checks.

This flaw stems from an incomplete remediation of CVE-2026-40189 and is addressed in goshs version 2.1.1.
Potential Impact
An unauthenticated attacker can read files that are intended to be protected by access control lists and block lists, leading to unauthorized disclosure of potentially sensitive data. The vulnerability does not affect integrity or availability but compromises confidentiality.
