{"id":"CVE-2021-3393","details":"An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.","aliases":["BIT-postgresql-2021-3393"],"modified":"2026-03-13T04:59:30.499013Z","published":"2021-04-01T14:15:13.657Z","related":["ALSA-2021:2372","MGASA-2021-0121","SUSE-SU-2021:0543-1","SUSE-SU-2021:0544-1","SUSE-SU-2021:0545-1","SUSE-SU-2021:0695-1","SUSE-SU-2021:1783-1","openSUSE-SU-2021:0423-1","openSUSE-SU-2024:11185-1","openSUSE-SU-2024:11186-1","openSUSE-SU-2024:11187-1","openSUSE-SU-2024:12387-1","openSUSE-SU-2024:13243-1","openSUSE-SU-2024:14360-1","openSUSE-SU-2025:15580-1"],"references":[{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202105-32"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210507-0006/"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1924005"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-3393.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"11.11"}]},{"events":[{"introduced":"12.0"},{"fixed":"12.6"}]},{"events":[{"introduced":"13.0"},{"fixed":"13.2"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
