CVE-2026-120059
Description
A flaw was found in postgresql-odbc. When processing updatable cursors, the driver improperly uses a server-provided column name as a format string when constructing query statements. A malicious database server or an attacker able to create a table with a specially crafted column name can cause the driver to read unrelated client memory. This issue can lead to information disclosure if sensitive client memory is transmitted to the server, or an application crash resulting in a Denial of Service (DoS).
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
