Description

Dockhand before 1.0.55 contains a path traversal vulnerability that allows authenticated users with stacks:edit to bypass the file-browser path guard by combining symlinks with '..' sequences. Attackers can read /proc/self/environ, the SQLite database, and the encryption key via /api/system/files/content, or move them using the stack relocate endpoint, exposing stored credentials.
