{"id":"CVE-2026-12044","summary":"pgAdmin 4: SQL injection in COMMENT ON ... IS '\u003cdescription\u003e' rendering across dialog templates","details":"SQL injection in pgAdmin 4 across every dialog template that renders ``COMMENT ON ... IS '\u003cdescription\u003e'`` for a user-supplied description field. The Jinja templates for Domains (and their constraints), Foreign Tables, Languages, and Event Triggers, plus the Views OID-lookup query, interpolated the description directly inside a single-quoted SQL literal -- ``'{{ data.description }}'`` -- instead of passing it through the ``qtLiteral`` escape filter. An authenticated pgAdmin user with permission to create or alter the affected object types could submit a description containing an apostrophe, break out of the literal and chain arbitrary SQL. The injected SQL runs under the PostgreSQL role the user is already authenticated as; for a connected role with ``COPY ... TO/FROM PROGRAM`` (typically PostgreSQL superuser), this chains to OS command execution on the PostgreSQL host. The defect does not cross a privilege boundary -- the user already has direct SQL access to that role through pgAdmin's Query Tool -- so the attacker gains no capability beyond what their database role already grants. The marginal impact captures bypass of any application-layer Query Tool gating an operator may have configured.\n\nThe defect was originally reported against the Domain Dialog ``description`` field; a code-wide audit identified sixteen sites of the same pattern across the templates listed above. The same review also surfaced ten related sinks in the pgstattuple/pgstatindex stats templates -- ``pgstattuple('{{schema}}.{{table}}')`` and the matching pgstatindex shape -- where ``qtIdent`` escapes embedded double quotes inside the identifier but not apostrophes, so a user with CREATE privilege on a schema could plant a table or index named ``foo'bar`` and a later stats viewer would render an unbalanced literal.\n\nFix is layered:\n\n  1. Sites: replace every ``'{{ x.description }}'`` with ``{{ x.description|qtLiteral(conn) }}`` (no surrounding quotes -- the filter wraps the value in escaped quotes itself). Plumb ``conn=self.conn`` through every ``render_template`` call that loads one of these templates. Also corrects a ``{ % elif`` Jinja typo in the foreign-table schema diff (dead branch). Rewrite the ten pgstattuple/pgstatindex stats sites to address the relation via OID + ``::oid::regclass`` cast (e.g. ``pgstattuple({{ tid }}::oid::regclass)``), eliminating the embedded literal-call form entirely so that bug-class can no longer recur there.\n\n  2. Driver hardening: ``qtLiteral`` (in ``utils/driver/psycopg3/__init__.py``) used to silently return the raw unescaped value when its ``conn`` argument was falsy. It now raises ``ValueError`` -- surfacing the entire bug class going forward. The change immediately uncovered eight latent plumbing bugs (in ``schemas/__init__.py``, ``schemas/functions/__init__.py``, ``schemas/tables/utils.py``, ``foreign_servers/__init__.py``, and seven sites in ``roles/__init__.py``) -- all fixed as part of this patch. The inner ``except`` block that swallowed adapter-level failures and returned the raw value is also removed, so unadaptable inputs raise instead of leaking unescaped values.\n\n  3. Regression tests: a per-template behavioural test renders each previously-vulnerable template with an apostrophe-injection payload and asserts the escaped fragment is present and the vulnerable fragment absent; a lint test walks every ``*.sql`` template flagging any ``'{{ ... }}'`` single-quote-wrapped interpolation against an explicit allowlist; unit tests cover the new qtLiteral fail-fast and inner-except raise paths.\n\nThis issue affects pgAdmin 4: from 1.0 before 9.16.","modified":"2026-07-15T01:48:51.270007704Z","published":"2026-06-18T23:37:16.202Z","database_specific":{"cna_assigner":"PostgreSQL","cwe_ids":["CWE-116","CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/12xxx/CVE-2026-12044.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/12xxx/CVE-2026-12044.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12044"},{"type":"REPORT","url":"https://github.com/pgadmin-org/pgadmin4/issues/10078"},{"type":"FIX","url":"https://github.com/pgadmin-org/pgadmin4/commit/2ae0d3610"},{"type":"FIX","url":"https://github.com/pgadmin-org/pgadmin4/commit/658bb585d"},{"type":"PACKAGE","url":"https://github.com/pgadmin-org/pgadmin4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pgadmin-org/pgadmin4","events":[{"introduced":"30397476da45e419a409710e7447bf0f10fcbcd9"},{"fixed":"888a053231923e6704b56165cf248db056252144"},{"fixed":"2ae0d3610"},{"fixed":"658bb585d"}],"database_specific":{"extracted_events":[{"introduced":"1.0"},{"fixed":"9.16"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:pgadmin:pgadmin_4:*:*:*:*:*:postgresql:*:*"}}],"versions":["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-2026-12044.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"}]}
