# PostgreSQL pg_dump: crafted object names let an attacker run SQL on restore

Link for people: https://infrastack.ai/live/CVE-2026-116318 (this .md is for agents)

pg_dump, the PostgreSQL backup tool, builds SQL from an inherited column's not-null constraint name without proper quoting. A user who can create database objects can plant a name that runs arbitrary SQL as whoever restores the dump.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `psql -c "SELECT version();"` or `pg_dump --version` and confirm the major version is `18`.
- Check the minor version is below `18.7`.

## Fix

- PostgreSQL 18: move to `18.7` or later.

## Timeline

- 2026-11-12T15:41:54+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-116318

## From the sources

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.
