{"id":"BIT-postgresql-2026-6470","summary":"PostgreSQL fails to check type USAGE privilege","details":"Missing authorization in PostgreSQL DDL commands allows an object creator to achieve denial of service against ALTER and DROP of the type, via creating a dependency on the type.  Many DDL operations did check the privilege, but assigning a range subtype and referencing the type from an SQL expression did not.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.","aliases":["CVE-2026-6470"],"modified":"2026-08-19T09:45:24.748101361Z","published":"2026-08-19T08:53:04.461Z","database_specific":{"cpes":["cpe:2.3:a:postgresql:postgresql:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6470"},{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2026-6470/"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Bitnami","purl":"pkg:bitnami/postgresql"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"14.24.0"},{"introduced":"15.0.0"},{"fixed":"15.19.0"},{"introduced":"16.0.0"},{"fixed":"16.15.0"},{"introduced":"17.0.0"},{"fixed":"17.11.0"},{"introduced":"18.0.0"},{"fixed":"18.5.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/postgresql/BIT-postgresql-2026-6470.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}],"schema_version":"1.9.0"}
