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."}],"references":[{"url":"https://github.com/pgadmin-org/pgadmin4/issues/10193","tags":["issue-tracking"]},{"url":"https://github.com/pgadmin-org/pgadmin4/commit/73b3218992cc37af6e10b7e54eaeed6ec293c6b2","tags":["patch"]},{"url":"https://github.com/pgadmin-org/pgadmin4/commit/f75452bfd0f786d0c071638919d48fc1d76f987d","tags":["patch"]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"Threat model: a low-privileged database user with CREATE TABLE/PUBLICATION/SUBSCRIPTION rights plants an apostrophe'd object name.
