Description

CVE-2026-35392 is a critical path traversal vulnerability in patrickhener's goshs, a SimpleHTTPServer written in Go. Versions prior to 2.0.0-beta.3 do not sanitize file paths during PUT uploads, allowing attackers to potentially write files outside the intended directory. This can lead to full compromise of confidentiality, integrity, and availability of the affected system. The vulnerability is fixed in version 2.0.0-beta.3.
