The req.admin.id fix activated reinjectCurrentAdmin(); hardening its preservation
logic (found across Codex review rounds of #811):
- MFA hijack: reinject wrote back only password_hash/is_active/
must_change_password, leaving a crafted backup's two_factor_* on the
operator's row — it could strip or replace their second factor. The email-
matched row is now updated with the operator's full AUTH set (login identity,
password, and all two_factor_* columns). Relationship/audit FKs (role_id,
created_by) are deliberately NOT forced from the snapshot: on a cross-instance
restore those pre-restore ids may be absent from the backup and would dangle
the FK (SQLite rolls back at commit); the restored row keeps its own valid
values.
- Cross-instance restore rollback / FK safety: reinject matched only by email,
so a backup shipping a different admin with the default `admin` username hit
UNIQUE(username) and rolled the whole restore back; email and username could
even collide on two different rows. Reconciliation is now non-destructive:
the email-matching row is updated in place (id preserved → restored FKs like
events.created_by stay valid); any different row holding the operator's
username is RENAMED, not deleted (deletion would fire ON DELETE actions /
dangle references); only when no row has the operator's email is a fresh row
inserted, with created_by nulled and an explicit max(id)+1 id (batchInsert
left the Postgres identity sequence unadvanced, so a sequence-based insert
could collide).
- Stale session after restore: admin_users ids shift on restore, but the
operator's live JWT is bound only to decoded.id (IP logged not enforced; the
backup controls password_changed_at). The route now revokes the token (result
checked and logged) and clears the admin cookie; the client redirects to a
fresh login via a sessionInvalidated flag. Cookie clear is the unconditional
guarantee.
Adds SQLite-backed reinject regression tests (in-place login/MFA restore with id
and FK columns preserved, username-only rename, email+username on different rows,
clean insert with created_by nulled) and the frontend redirect on
sessionInvalidated.
Deferred (design decisions / pre-existing, need a Postgres test env — see PR
discussion): global "invalidate all pre-restore sessions" cutoff; preserving the
operator's ROLE semantics across an RBAC-table replace; and resyncing Postgres
identity sequences after any restore (batchInsert leaves them behind max(id) —
pre-existing, affects every restored table).
Downloading a portable backup is a "make a backup" action, so it belongs
next to "Run Backup Now" on the Dashboard, not under Restore. Split the
combined card into PicpeakExportCard (Dashboard) and PicpeakRestoreCard
(Restore). The manifest stays bundled inside the .picpeak, so there is no
separate manifest-only download for the portable format.
Adds a self-contained "Portable backup (.picpeak)" card to the Restore
tab, completing the GUI-only roundtrip:
- Download: optional "include original photos" toggle + a prominent
plaintext-secrets warning, streams the file via a blob download.
- Restore: file picker → destructive confirmation modal ("replaces ALL
data except your current account, cannot be undone") → multipart upload
to /admin/backup/picpeak/import → success summary. If the backup uses
external media, shows a banner to reconfigure the mount, with a docs link.
Kept separate from the legacy RestoreWizard (different format/flow). en+de
strings added; dark-mode variants throughout.
