CVE-2026-17566

Description

A flaw was found in pgAdmin 4, a management tool for PostgreSQL databases. The Import/Export Data feature incorrectly processes certain user-provided SQL queries, specifically regarding how backslash characters are interpreted. This vulnerability allows an authenticated remote attacker, with specific permissions, to bypass security checks and execute unauthorized commands on the server running pgAdmin 4. Successful exploitation could lead to remote code execution, giving the attacker full control over the affected system.

Statement

This flaw does not affect Red Hat products, but only the Fedora community project.

Understanding the Weakness (CWE)

Confidentiality,Integrity,Availability,Non-Repudiation

Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities

Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
