What is CVE-2026-116314?

A vulnerability in PostgreSQL's pg_restore can lead to arbitrary code execution by allowing a non-plain archive provider to exploit improper input validation. When handling a crafted archive, malicious users could execute arbitrary code as the operating system user running pg_restore. While legitimate archive data may execute SQL code at the restore destination, it does not authorize arbitrary execution within the pg_restore process itself. This issue affects several PostgreSQL versions, emphasizing the importance of updating to mitigate security risks.

Affected Version(s)

PostgreSQL 18 < 18.7

PostgreSQL 17 < 17.12

PostgreSQL 16 < 16.16
