Diego Imbert 339c259fce fix(drafts): close variable draft-secret laundering oracle (sentinel + rehydrate)
save_draft encrypts secret variable values with the workspace key, but
the ciphertext was round-tripped to the client and the deploy endpoints
decrypted whatever $encrypted: ciphertext the client submitted
(variables.rs create/update). Any workspace member who can write a
variable path could take an arbitrary workspace-key ciphertext (another
user's secret draft via GET /drafts/get with only path-read, or a
deployed secret's stored value) and submit it as their own secret
variable's value — the server decrypted it and, since they own the path,
they read the plaintext back. That bypasses the audited decrypt_secret
permission.

Fix: the ciphertext never leaves the server. get_variable swaps a draft
secret's $encrypted: value for an opaque $draft_secret sentinel (both the
draft overlay and the draft-only inner stand-in). On deploy the client
sends the sentinel back and the server rehydrates the plaintext from the
caller's OWN draft row — the only ciphertext it ever decrypts is one it
encrypted for this exact (workspace, path, email). A raw $encrypted:
submitted by a client is now rejected outright.

Windmill Backend

This folder holds all backend components, the src/ folder only contains files used to build the "root" binary.

Components

name description
windmill-api The API server, exposing functionality to other components and the frontend
windmill-audit Contains audit functionality, allowing different components to record important actions
windmill-common Common code shared by all crates
windmill-queue Contains job & flow queuing functionality, commonly written to by the API server and read from by workers
windmill-worker The worker. Used to process and execute flows & jobs.
parsers Contains code to parse signatures in different langauges.
