{"id":"BIT-postgresql-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":["CVE-2021-3393"],"modified":"2025-04-03T14:40:37.652Z","published":"2024-03-06T11:04:37.907Z","database_specific":{"cpes":["cpe:2.3:a:postgresql:postgresql:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1924005"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202105-32"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20210507-0006/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-3393"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Bitnami","purl":"pkg:bitnami/postgresql"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"11.11.0"},{"introduced":"12.0.0"},{"fixed":"12.6.0"},{"introduced":"13.0.0"},{"fixed":"13.2.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/postgresql/BIT-postgresql-2021-3393.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.7.3"}
