CVE-2026-116311
Description
A flaw was found in PostgreSQL. An authenticated database user can execute the DROP OWNED command to improperly remove their role from restrictive Row-Level Security (RLS) policies. By bypassing these access controls, the user can view or modify table rows that were intended to be restricted.
Statement
This vulnerability is rated as a Moderate impact issue for Red Hat products because successful exploitation requires an authenticated database user with existing connection privileges and specifically targets environments enforcing restrictive row-level security (RLS) policies. While an authenticated role can circumvent these restrictive rules to access or alter protected table rows, the flaw does not grant database superuser privileges or compromise the underlying host system. Typical PostgreSQL deployments that do not rely on restrictive row-level security for multi-tenant data separation are not exposed to this risk.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
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.
