{"id":"AZL-95705","summary":"CVE-2026-18408 affecting package postgresql 16.14-1","details":"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 \\restrict meta-command input expansion.  The fix for CVE-2025-8714 introduced \\restrict and \\unrestrict to block this attack, but \\unrestrict itself was sufficient for an attack.  pg_dumpall is also affected.  pg_restore is affected when used to generate a plain-format dump.  Non-core use of \\restrict would be affected, but we've not identified non-core use.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.","modified":"2026-08-29T05:27:27Z","published":"2026-08-13T13:17:48Z","upstream":["CVE-2026-18408"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18408"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"16.14-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95705.json"}}],"schema_version":"1.9.0"}
