{"id":"CVE-2026-17348","summary":"pgAdmin 4: Missing authentication decorator on Constraints, preferences, Debugger and Schema Diff routes allows unauthenticated access in SERVER mode (incomplete fix for CVE-2026-12046)","details":"In SERVER mode, pgAdmin 4 enforces authentication per route via the @pga_login_required decorator; the application's before_request hook only handles desktop-mode auto-login and the Kerberos/Webserver-auth redirect, so any route shipped without the decorator is reachable without authentication (CWE-306). 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.","modified":"2026-08-07T11:49:51.121249890Z","published":"2026-07-31T15:59:18.714Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/17xxx/CVE-2026-17348.json","cna_assigner":"PostgreSQL","cwe_ids":["CWE-306"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/17xxx/CVE-2026-17348.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-17348"},{"type":"REPORT","url":"https://github.com/pgadmin-org/pgadmin4/issues/10194"},{"type":"FIX","url":"https://github.com/pgadmin-org/pgadmin4/commit/24fdcf0f58591c87ada31366c01e1af180eceb05"},{"type":"PACKAGE","url":"https://github.com/pgadmin-org/pgadmin4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pgadmin-org/pgadmin4","events":[{"introduced":"30397476da45e419a409710e7447bf0f10fcbcd9"},{"fixed":"067f7af2274cf034623426d2b74a7695018a5f1f"},{"fixed":"24fdcf0f58591c87ada31366c01e1af180eceb05"}],"database_specific":{"cpe":"cpe:2.3:a:pgadmin:pgadmin_4:*:*:*:*:*:postgresql:*:*","extracted_events":[{"introduced":"1.0"},{"fixed":"9.17"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["REL-9_16","REL-9_15","REL-9_14","REL-9_13","REL-9_12","REL-9_11","REL-9_10","REL-9_9","REL-9_8","REL-9_7","REL-9_6","REL-9_5","REL-9_4","REL-9_3","REL-9_2","REL-9_1","REL-9_0","REL-8_14","REL-8_13","REL-8_12","REL-8_11","REL-8_10","REL-8_9","REL-8_8","REL-8_7","REL-8_6","REL-8_5","REL-8_4","REL-8_3","REL-8_2","REL-8_1","REL-8_0","REL-7_8","REL-7_7","REL-7_6","REL-7_5","REL-7_4","REL-7_3","REL-7_2","REL-7_1","REL-7_0","REL-6_21","REL-6_20","REL-6_19","REL-6_18","REL-6_17","REL-6_16","REL-6_15","REL-6_14","REL-6_13","REL-6_12","REL-6_11","REL-6_10","REL-6_9","REL-6_8","REL-6_7","REL-6_6","REL-6_5","REL-6_4","REL-6_3","REL-6_2","REL-6_1","REL-6_0","REL-5_7","REL-5_6","REL-5_5","REL-5_4","REL-5_3","REL-5_2","REL-5_1","REL-5_0","REL-4_30","REL-4_29","REL-4_28","REL-4_27","REL-4_26","REL-4_25","REL-4_24","REL-4_23","REL-4_22","REL-4_21","REL-4_20","REL-4_19","REL-4_18","REL-4_17","REL-4_16","REL-4_15","REL-4_14","REL-4_13","REL-4_12","REL-4_11","REL-4_10","REL-4_9","REL-4_8","REL-4_7","REL-4_6","REL-4_5","REL-4_4","REL-4_3","REL-4_2","REL-4_1","REL-4_0","REL-3_6","REL-3_5","REL-3_4","REL-3_3","REL-3_2","REL-3_1","REL-3_0","REL-2_1","REL-2_0","REL-2_0-RC2","REL-2_0-RC1","REL-1_6","REL-1_5","REL-1_4","REL-1_3","REL-1_2","REL-1_1","REL-1_0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-17348.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
