PostgreSQL optimizer statistics allow a user to read sampled data within a view that the user cannot access.  Separately, statistics allow a user to read sampled data that a row security policy intended to hide.  PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process.  Prior to this release, a user could craft a leaky operator that bypassed view access control lists (ACLs) and bypassed row security policies in partitioning or table inheritance hierarchies.  Reachable statistics data notably included histograms and most-common-values lists.  CVE-2017-7484 and CVE-2019-10130 intended to close this class of vulnerability, but this gap remained.  Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected.

Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql meta-commands.  pg_dumpall is also affected.  pg_restore is affected when used to generate a plain-format dump.  This is similar to MySQL CVE-2024-21096.  Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected.

Improper neutralization of newlines in pg_dump in PostgreSQL allows a user of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql meta-commands inside a purpose-crafted object name.  The same attacks can achieve SQL injection as a superuser of the restore target server.  pg_dumpall, pg_restore, and pg_upgrade are also affected.  Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected.  Versions before 11.20 are unaffected.  CVE-2012-0868 had fixed this class of problem, but version 11.20 reintroduced it.
