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.
