windmill/backend/tests/jobs_read_auth.rs

//! Regression test for the single-job read authorization bypass.
//!
//! The single-job read endpoints (`/jobs_u/get`, `/completed/get`,
//! `/completed/get_result`, `/get_args`, `/get_logs`, `/getupdate`, ...) fetch a
//! job through the root DB handle, filtered only by job id + workspace. That is
//! required for the unauthenticated approval / public-trigger / anonymous-job
//! flows, but for a *logged-in* user it meant any workspace member — including a
//! plain viewer with no ACL on the runnable — could read another user's job
//! args/result/logs simply by obtaining the job UUID, even though the same job is
//! hidden from them in `jobs/list` (RLS-filtered) and the underlying script
//! returns 404.
//!
//! The fix (`require_job_read_access`) gates the authenticated case: a caller may
//! read a job they created (covers app components / webhooks / their own runs)
//! or one visible to them under the same RLS as `jobs/list` (admins bypass);
//! otherwise 404. Unauthenticated access is unchanged (anonymous jobs only).
//!
//! This test pins down, against the `jobs_read_auth` fixture:
//!   - a viewer is denied the victim job's full record / result / result_maybe /
//!     args / logs / live update by UUID, and the secret never appears in the
//!     body (the core fix; pre-fix these returned 200 with the secret),
//!   - the job's owner and an admin can still read it (no over-blocking),
//!   - the "app component" affordance survives: a viewer who *launched* a job
//!     (created_by) running as someone else's identity can still read its result,
//!   - unauthenticated behavior is unchanged: anonymous jobs readable, the
//!     non-anonymous victim job rejected,
//!   - `queue/cancel` and `queue/force_cancel` are gated by that same access, so
//!     a viewer cannot kill a run hidden from them while its owner still can, and
//!     force cancel gates on the ancestor it actually kills rather than the id in
//!     the URL.
