{"id":"AZL-113678","summary":"CVE-2026-116303 affecting package postgresql 16.15-1","details":"Missing authorization in PostgreSQL type conversion allows a database user to invoke a cast function despite lacking EXECUTE privilege on that function, via foreign keys, to_json(), and others.  A successful attack requires the attacker to search each database for access-restricted cast functions and identify confidentiality impact specific to each function implementation found.  There are few or no practical examples of an access-restricted cast function or of a cast function having confidentiality impact.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.","modified":"2026-11-13T14:17:11.055645624Z","published":"2026-11-12T15:17:37Z","upstream":["CVE-2026-116303"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-116303"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"16.15-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113678.json"}}],"schema_version":"1.9.2"}
