Vulnerability Title
PostgreSQL pg_dump tar restore.sql fails to block psql command injection
Source: CVE Program / CVE List V5
Vulnerability Description
Untrusted data inclusion in PostgreSQL pg_dump tar-format restore.sql allows a compromised origin server to execute arbitrary code as the client operating system account running psql, via the predictable restriction key in restore.sql. This is a gap in the fix for CVE-2025-8714. restore.sql is undocumented. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
