Publication date: 2026-02-06

Last updated on: 2026-02-19

Assigner: GitHub, Inc.

Description

Sliver is a command and control framework that uses a custom Wireguard netstack. Prior to 1.6.11, a path traversal in the website content subsystem lets an authenticated operator read arbitrary files on the Sliver server host. This is an authenticated path traversal / arbitrary file read issue, and it can expose credentials, configs, and keys. This vulnerability is fixed in 1.6.11.

Attack-Flow Graph

Executive Summary

This vulnerability exists in Sliver, a command and control framework that uses a custom Wireguard netstack. Prior to version 1.6.11, there is a path traversal issue in the website content subsystem that allows an authenticated operator to read arbitrary files on the Sliver server host.

Because of this path traversal and arbitrary file read vulnerability, an attacker with authentication can access sensitive files such as credentials, configuration files, and keys stored on the server.

This issue is fixed in Sliver version 1.6.11.

Impact Analysis

The vulnerability can have significant impacts because it allows an authenticated operator to read arbitrary files on the server hosting Sliver.

Exposure of sensitive credentials that could be used to escalate privileges or access other systems.
Disclosure of configuration files that might reveal system or network details.
Access to cryptographic keys that could compromise encrypted communications or data.

Overall, this could lead to unauthorized access, data breaches, and compromise of the security of the affected system.
