CVE-2026-25760Public exploitNetwork attack vector

Authenticated file read via stored path traversal

Published Feb 6, 2026 · Updated Feb 6, 2026

Path traversal in Sliver before 1.6.11 allows remote authenticated users to read files accessible to the server OS account. Website.ToProtobuf joins an operator-controlled stored Path to the web-content directory and reads the result without containment, allowing traversal segments to escape that directory. An operator account with PermissionAll is required, and exposure is limited to files readable by the server process, including configs, keys, tokens, and logs.
