Critical

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions postgresql versions prior to 13.2 postgresql versions prior to 12.6 postgresql versions prior to 11.11
Description An information leak was discovered in postgresql. A user with UPDATE permission but not SELECT permission to a particular column could craft queries that might disclose values from that column in error messages under certain circumstances. This could allow an attacker to obtain information stored in a column they are allowed to write but not read.
Recommendations For versions prior to 13.2, update to version 13.2 or later to resolve the issue. For versions prior to 12.6, update to version 12.6 or later to resolve the issue. For versions prior to 11.11, update to version 11.11 or later to resolve the issue.
