Dockhand before 1.0.54 contains a path traversal vulnerability that allows authenticated users to read, overwrite, and delete .env files outside the stacks root by double-encoding the stack name. Attackers can send %252e%252e sequences to /api/stacks/[name]/env/raw to disclose cross-environment secrets, write into protected directories, or poison deployment variables.
