{"id":"CVE-2026-17346","summary":"pgAdmin 4: SQL injection via unescaped object names in index Statistics and publication/subscription dependency views (incomplete fix for CVE-2026-12044)","details":"The fix for CVE-2026-12044 in pgAdmin 4 9.16 hardened qtLiteral and switched sixteen COMMENT ON / pgstattuple / pgstatindex templates to it, but missed several sinks that had been placed in test_sql_string_literal_lint.py's ALLOWLIST on the incorrect assumption that schema, table, publication, and subscription names sourced from pg_catalog via the browser tree could never contain an apostrophe. PostgreSQL permits arbitrary characters in quoted identifiers, so a low-privileged user able to CREATE TABLE, CREATE PUBLICATION, or CREATE SUBSCRIPTION can plant an apostrophe'd object name that breaks out of the unescaped '{{ name }}' template interpolation the moment any user (including a higher-privileged one) opens that object's Statistics or Dependencies tab, allowing arbitrary SQL statement injection in the viewing user's database session.\n\nAffected sinks: the Index Statistics query for all-indexes listing (coll_stats.sql, both the 16_plus and default PostgreSQL-version template variants -- distinct from the single-index stats.sql path already fixed in CVE-2026-12044), and the publication and subscription dependencies.sql / get_position.sql templates (both the pg and ppas/EPAS dialect variants for publications).\n\nFix switches all of these templates to qtLiteral(conn) for name interpolation, and updates publications/__init__.py and subscriptions/__init__.py to pass conn=self.conn into the dependencies.sql render_template call so the qtLiteral filter has a connection to quote against. The corresponding ALLOWLIST entries in test_sql_string_literal_lint.py are removed now that these sinks are properly escaped rather than merely assumed safe. A behavioral regression test renders each fixed template with a stacked-statement apostrophe payload and asserts both that the object name appears exactly as qtLiteral-escaped and that the rendered SQL parses as exactly one statement, verifying the assertion genuinely fails against the pre-patch raw-interpolation form.\n\nThis issue affects pgAdmin 4: the Index Statistics sink from 1.0, and the Publications/Subscriptions sinks from 5.0, both before 9.17.","modified":"2026-08-02T03:45:59.558313391Z","published":"2026-07-31T15:59:13.136Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/17xxx/CVE-2026-17346.json","unresolved_ranges":[{"extracted_events":[{"introduced":"1.0"},{"fixed":"9.17"},{"introduced":"5.0"},{"fixed":"9.17"}],"source":"AFFECTED_FIELD"},{"extracted_events":[{"fixed":"9.17"}],"source":"DESCRIPTION"}],"cna_assigner":"PostgreSQL","cwe_ids":["CWE-89"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/17xxx/CVE-2026-17346.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-17346"},{"type":"REPORT","url":"https://github.com/pgadmin-org/pgadmin4/issues/10193"},{"type":"FIX","url":"https://github.com/pgadmin-org/pgadmin4/commit/73b3218992cc37af6e10b7e54eaeed6ec293c6b2"},{"type":"FIX","url":"https://github.com/pgadmin-org/pgadmin4/commit/f75452bfd0f786d0c071638919d48fc1d76f987d"},{"type":"PACKAGE","url":"https://github.com/pgadmin-org/pgadmin4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pgadmin-org/pgadmin4","events":[{"introduced":"0"},{"fixed":"73b3218992cc37af6e10b7e54eaeed6ec293c6b2"},{"fixed":"f75452bfd0f786d0c071638919d48fc1d76f987d"}],"database_specific":{"source":"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","REL-1_0-RC1","REL-1_0-BETA4","REL-1_0-BETA3","REL-1_0-BETA2","REL-1_0-BETA1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-17346.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
