{"id":"BIT-postgresql-2025-8713","summary":"PostgreSQL optimizer statistics can expose sampled data within a view, partition, or child table","details":"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.","aliases":["CVE-2025-8713"],"modified":"2025-08-18T08:59:39.068240Z","published":"2025-08-18T08:11:23.116Z","database_specific":{"cpes":["cpe:2.3:a:postgresql:postgresql:*:*:*:*:*:*:*:*"],"severity":"Low"},"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-8713"},{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2025-8713/"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Bitnami","purl":"pkg:bitnami/postgresql"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"13.22.0"},{"introduced":"14.0.0"},{"fixed":"14.19.0"},{"introduced":"15.0.0"},{"fixed":"15.14.0"},{"introduced":"16.0.0"},{"fixed":"16.10.0"},{"introduced":"17.0.0"},{"fixed":"17.6.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/postgresql/BIT-postgresql-2025-8713.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.7.3"}
