# PostgreSQL: crafted pg_restore archive runs code as the restoring user

Link for people: https://infrastack.ai/live/CVE-2026-116314 (this .md is for agents)

A crafted archive passed to pg_restore can execute arbitrary operating system code as the user running pg_restore. An attacker who supplies the archive gets code execution on the machine running the restore.

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

## How to check

- Run `psql -c "SHOW server_version;"` or `pg_restore --version` to find the installed version
- Check whether any version is below `18.7`, `17.12`, `16.16`, `15.20` or `14.25`

## Fix

- Upgrade PostgreSQL to `18.7`, `17.12`, `16.16`, `15.20` or `14.25` (the fixed release for each major line)

## From the sources

Improper input validation in PostgreSQL pg_restore allows a non-plain archive provider to execute arbitrary code as the operating system user running pg_restore, via a crafted archive.  Note a contrast: crafted archive data may legitimately cause arbitrary SQL to execute at the restore destination, but it does not legitimately confer arbitrary code execution in the pg_restore OS process.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
