CVE-2025-12817
Description
A vulnerability has been identified in PostgreSQL’s CREATE STATISTICS command where the database does not check that the user has the required schema CREATE privilege. A table owner user could create a statistics object in any schema, blocking other users who legitimately hold CREATE STATISTICS permissions from creating objects with the same name. This results in a denial-of-service of the statistics creation functionality.
Statement
This issue is rated Low severity by Red Hat Product Security, because exploitation is straightforward once an attacker already holds table-owner privileges. The attack complexity is Low, as no unusual conditions, timing requirements, or unpredictable states are needed; a table owner can simply choose any schema name and intentionally create a statistics object with a conflicting name, which is only trivial to perform and does not require prior knowledge beyond selecting an arbitrary identifier. The availability impact remains Low, since only the creation of a specific statistics object is blocked and normal database operations continue without disruption. There is no confidentiality or integrity impact, and the flaw does not allow privilege escalation. For these reasons, despite a Medium-range CVSS score, the overall impact to Red Hat products is considered Low.
Mitigation
No mitigation is currently available that meets Red Hat Product Security’s standards for usability, deployment, applicability, 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).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data; Read Files or Directories
An attacker could read sensitive data, either by reading the data directly from a data store that is not restricted, or by accessing insufficiently-protected, privileged functionality to read the data.
Integrity
Technical Impact: Modify Application Data; Modify Files or Directories
An attacker could modify sensitive data, either by writing the data directly to a data store that is not restricted, or by accessing insufficiently-protected, privileged functionality to write the data.
Access Control
Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism
An attacker could gain privileges by modifying or reading critical data directly, or by accessing privileged functionality.
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
An attacker could gain unauthorized access to resources on the system and excessively consume those resources, leading to a denial of service.
