Summary

The Group Role dialog's Membership tab only enabled the add/remove member controls (the "+" icon) for superusers and CREATEROLE holders. A user who was themselves granted ADMIN OPTION on that specific role - and who can therefore GRANT/REVOKE its membership directly in SQL - had no way to add other members through the UI, and hit "The current user does not have permission to update the role." server-side if they tried some other way in.

  • Frontend: the role schema now also enables the Members collection when the connected user appears in the role's own member list with admin: true.
  • Backend: permission.sql now also reports whether the connecting user holds ADMIN OPTION on the target role (a direct pg_auth_members lookup, matching how the role's member list is already built elsewhere in this module). The update permission check lets such a user through, but the update handler then restricts what they're allowed to submit to rolmembers changes only, so this can't be used to escalate other role attributes (superuser, CREATEROLE, password, etc.) they otherwise have no permission to change. The role's oid, which the properties dialog sends with every edit, is allowed alongside rolmembers.

Fixes #9450.

Test plan

  • Verified the underlying pg_auth_members admin-option query directly against a live PostgreSQL 18 server, both for a role with and without admin option on the target
  • Added a unit test (test_role_check_permission_unit_test.py) covering the permission carve-out: allowed for update with admin option, still forbidden for drop, unaffected for superusers
  • Added Jest coverage for the new isMemberAdmin/membersReadOnly schema logic
  • python regression/runtests.py --pkg browser.server_groups.servers.roles passes with no regressions against a live PostgreSQL 18 server
  • yarn jest regression/javascript/schema_ui_files/role.ui.spec.js passes (6/6)

Summary by CodeRabbit

  • New Features

    • Users with ADMIN OPTION can manage role memberships without unrestricted role-editing permissions.
    • Authorized administrators can edit or remove memberships while other role settings remain read-only.
  • Bug Fixes

    • Membership-only role updates are accepted, including when validation adjusts submitted data.
    • Requests with a JSON array instead of an object are rejected with a clear client error.
    • Unauthorized role changes continue to be rejected.
  • Tests

    • Added coverage for ADMIN OPTION, superuser access, read-only behavior, and membership-only updates.

Walkthrough

Role permission handling recognizes ADMIN OPTION. Eligible users can edit role membership, while other role changes remain restricted. The role UI enables membership editing for these users. The request wrapper rejects JSON bodies that are not objects.

Changes

Role membership ADMIN OPTION

Layer / File(s) Summary
ADMIN OPTION permission metadata
web/pgadmin/browser/server_groups/servers/roles/templates/roles/sql/default/permission.sql
The permission query returns has_admin_option for the target role.
Membership update validation
web/pgadmin/browser/server_groups/servers/roles/__init__.py, web/pgadmin/browser/server_groups/servers/roles/tests/test_role_check_permission_unit_test.py
The request wrapper rejects non-object JSON bodies with HTTP 428 before capturing request keys. Tests cover ADMIN OPTION permission checks, request-key handling, membership-only updates, and rejection of non-object bodies.
Membership editing state
web/pgadmin/browser/server_groups/servers/roles/static/js/role.ui.js, web/regression/javascript/schema_ui_files/role.ui.spec.js
The UI uses membersReadOnly for membership editing and deletion. Tests cover ordinary members, ADMIN OPTION members, and superusers.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 3b25a

ADMIN OPTION membership editing is consistently supported across the backend and UI, with no actionable merge-blocking risk identified.

Cleaned this branch up:

  • Rebased onto current upstream/master and dropped two commits that had ridden along from an unrelated personal dev stack (the Helm existingSecret fix from Fix existingSecret in helm Deployment #10214 and the REINDEX CONCURRENTLY placement fix from Maintenance dialog REINDEX generates invalid SQL when "Concurrently" is enabled ("syntax error at or near CONCURRENTLY") #10251) - neither belongs to this PR. It now carries only its own two commits.
  • Addressed the remaining CodeRabbit finding: extended test_role_check_permission_unit_test.py with a test that drives RoleView.update() through its real decorator chain (check_precondition -> validate_request -> update), with the driver/connection/SQL rendering mocked out, submitting a rolmembers-only body as an ADMIN OPTION holder and asserting it isn't rejected with 403. The prior test only re-implemented the guard's logic by hand and never called the real path.

Targeted test run (browser.server_groups.servers.roles.tests.test_role_check_permission_unit_test) passes, all 3 cases.

Carrying a CodeRabbit finding over from #10330, where it was raised against an unrebased branch that still had this work stacked on it, so it landed on the wrong PR:

Check the original request fields before membership normalization.
validate_request expands a valid rolmembers request with internal keys such as rol_members_list and rol_members_revoked_list before this check runs. Therefore, every valid membership-only update fails the subset test and returns 403.

It was a real bug, and it is already fixed on this branch. The version it was raised against (4173ddf, the copy carried on #10330's branch) had not set(self.request) <= {'rolmembers'}, which does read the mutated dict and would have 403d every membership-only update. Current head has self.request_keys, captured in validate_request before any of the validators run, and test_role_check_permission_unit_test.py covers it both ways: it asserts that the mutated dict is no longer a subset of {'rolmembers'} and that the captured key set still is, and there is a request-level test submitting a rolmembers-only update.

Nothing to do here, recording it so the finding is not lost.

Comment thread web/pgadmin/browser/server_groups/servers/roles/__init__.py
…min-org#9450)

A role's membership tab only enabled the add/remove member controls
for superusers and CREATEROLE holders, so a user who was themselves
granted ADMIN OPTION on that role (and can therefore GRANT/REVOKE its
membership at the SQL level) had no way to add other members, and hit
a permission error server-side if they tried anyway.

The role UI schema now also allows membership changes when the
current user is a member of the role with admin=true. The backend
mirrors this: permission.sql reports whether the connecting user
holds ADMIN OPTION on the target role, and the update handler lets
such a request through only when it's restricted to rolmembers
changes, so this can't be used to escalate other role attributes.
_validate_rolemembers() mutates the request dict in place, adding
derived keys such as rol_members_list and rol_members_revoked_list.
The membership-only update guard in RoleView.update() checked those
mutated keys against {'rolmembers'}, so a valid ADMIN OPTION request
containing only rolmembers was wrongly rejected as forbidden.

Capture the client-supplied keys before validate_request() runs the
validators, and check against that snapshot instead. Adds a regression
test for the rolmembers-only update path.
… guard

The existing regression test for the membership-only update guard
re-implemented _check_permission()/_validate_rolemembers() logic by hand
instead of calling validate_request() or RoleView.update(), so it
wouldn't catch a regression in how those decorators interact.

Add a test that drives RoleView.update() through its real decorator
chain (check_precondition -> validate_request -> update), with the
driver/connection/SQL rendering mocked out, submitting a
rolmembers-only body as an ADMIN OPTION holder and asserting the
request is not rejected with 403.
The properties dialog sends the role's 'oid' with every edit, because
SchemaState.changes() appends the schema's idAttribute to the payload.
The membership-only guard only allowed {'rolmembers'}, so a real save
from the dialog by an ADMIN OPTION holder was still rejected with 403;
the end-to-end test missed it because it built a body without 'oid'.

Allow 'oid' as well (the role is identified by 'rid' from the URL, not
by that value), send the dialog's real payload shape in the test, and
assert that adding any other attribute is still forbidden.
validate_request() now takes set(data) to record the client-supplied
keys, which raises TypeError for a JSON array body such as [{}]. Return
a precondition error when the body is not a JSON object, and cover it
in the update test.
