CVE-2025-8713 [HIGH] CWE-1230 postgresql: PostgreSQL optimizer statistics can expose sampled data within a view, partition, or child table
postgresql: PostgreSQL optimizer statistics can expose sampled data within a view, partition, or child table
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
