What is CVE-2026-40885?

The goshs SimpleHTTPServer, versions 2.0.0-beta.4 to 2.0.0-beta.5, exposes a critical file access vulnerability. When deployed without global basic authentication, the server leaks file-based Access Control List (ACL) credentials through its public collaborator feed. Unauthorized requests to protected folders are logged before authentication, allowing an unauthenticated user to capture sensitive headers. This can lead to unauthorized reading, uploading, overwriting, and deleting of files within the safeguarded directory. The vulnerability has been addressed in version 2.0.0-beta.6.

Affected Version(s)

goshs >= 2.0.0-beta.4, < 2.0.0-beta.6
