Doc Text:
A flaw was found in PostgreSQL's pg_dump utility. An authenticated database user with permission to create objects can trigger a SQL injection vulnerability by defining an inherited column with a child-local constraint whose name requires quoting. When the resulting database dump is restored, this flaw allows arbitrary SQL commands to be executed with the privileges of the restoring user.

Description OSIDB Bzimport 2026-11-12 14:33:55 UTC
SQL injection in PostgreSQL pg_dump allows an object creator to execute arbitrary SQL as the user restoring the dump, via an inherited column having a child-local not-null constraint whose name requires quoting.  Within major version 18, minor versions before PostgreSQL 18.7 are affected.  Versions before PostgreSQL 18 are unaffected.
