CVE-2026-116314 PUBLISHED

PostgreSQL pg_restore executes arbitrary code due to missing non-plain archive validation

Assigner: PostgreSQL
Reserved: 26.10.2026 Published: 12.11.2026 Updated: 12.11.2026

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.
