This is the same defect class previously fixed as CVE-2026-12046 (the sqleditor close/update_connection routes).\n\nA follow-up sweep, prompted by a report describing an incomplete fix for CVE-2026-12046, found further routes missing @pga_login_required: the Constraints blueprint's nodes and proplist (object listing) routes and its delete route (a state-mutating DELETE that removes table constraints); preferences.get_all_cli (GET, discloses all CLI-settable preference values); debugger.close (DELETE); and schema_diff.close (DELETE). An unauthenticated network client could therefore enumerate constraint metadata, delete table constraints, read preference values, and force-close debugger or schema-diff sessions belonging to other users, without ever authenticating.\n\nFix adds the missing @pga_login_required decorator (and the corresponding import to the Constraints module) to each of these routes. The change is decorator-only; no behavioral changes to the underlying handlers.\n\nThis issue affects pgAdmin 4 in SERVER mode: the Constraints and Debugger routes from 1.0, the Schema Diff close route from 4.18, and preferences.get_all_cli from 8.2, all before 9.17."}], "references": [{"url": "https://github.com/pgadmin-org/pgadmin4/issues/10194", "tags": ["issue-tracking"]}, {"url": "https://github.com/pgadmin-org/pgadmin4/commit/24fdcf0f58591c87ada31366c01e1af180eceb05", "tags": ["patch"]}], "metrics": [{"format": "CVSS", "scenarios": [{"lang": "en", "value": "Threat model: an unauthenticated network client sends requests directly to the affected routes on a SERVER-mode pgAdmin deployment, bypassing the login page entirely since these routes never checked for a session.

Integrity is Low: the delete route removes a table constraint, a real but narrow and recoverable schema change (the constraint definition can be recreated; no data rows are lost), and the close routes only terminate another user's debugger/schema-diff session state. Availability is Low, reflecting that same session-termination nuisance.
